Spirit -- The word translated as "spirit" primarily means "breath," "wind," a "non-material being," and "blast." Like "spirit" in English, it can also mean "attitude" or "motivation.' It also means the "breath of life," from which we get to "spirit" and "spiritual." Its meaning as "the breath of life" is brought out by the idea of creating life. Its meaning as "spiritual" is brought out by the contrast with "physical." See this article.

of -- This word "of"  comes from the genitive case of the following word that requires the addition of a preposition in English.  The most common is the "of" of possession

Lord -- The word translated as "master" is the same word that is often translated as "Lord" or "the Lord" in the NT. It also means "lord," "master of the house," and "head of the family." It is the specific terms for the master of slaves or servants, but it was a common term of respect both for those in authority and who were honored. It was the term people used to address Christ, even though he had no formal authority. Today, we would say "boss" or "chief." For the sake of consistency, this should be the Greek word translated as "master."

is -- There is no verb "is" here in the Greek source but it is implied by the noun in the form of a subject having no verb associated with it.

on -- The word translated as "on" means "on," "over," "upon," "for,"  "against," "before," "after," "during," "by" "in the case of."

me, -- "Me" is the regular first-person pronoun in Greek as the object of the verb or preposition. As the object of a preposition, an accusative object indicates movement towards something or a position reached as a result of that movement.

because -- (CW) This preposition  means "on account of," "as far as regards," "in consequence of," and "because." This preposition is usually paired with the noun "sake" in English.

missing "of which"  -- (MW) The untranslated word  "of which" is a demonstrative pronoun ("this" "that"), but it often acts as a pronoun, "he," "she," "it," "which," "what," "who," "whosoever," "where," "for which reason," and many similar meanings.

he -- This is from the third-person, singular form of the verb.

proclaim the gospel  -- "Proclaim good news" is from a verb that means "to bring good news", and "to announce". It is in form where the subject acts on himself or does something for themselves, or, in this case, "myself." "Preach" is not the specific meaning of the word in this situation.

to -- This word "to" comes from the dative case of the following word that requires the addition of a preposition in English. The most common is a "to" for the English indirect object.

has -- This helping verb "has" indicates that the verb is the tense indicating an action completed in the past.

sent --- (CW) The "sent" here is a word that means "to send off" and "dispatch." It is the source of our word "apostle." This word is not the simple "send" but a more complex one that means "send out" or "send from."

me -- "Me" is the regular first-person pronoun in Greek as the object of the verb or preposition.

to -- This "to" is added because the infinitive form of the verb requires a "to" in English.

proclaim --  The word translated as "proclaim" means "to act as a herald," "to proclaim," and "to declare." It does not have the relationship to discussing the Divine that our word "preach" does nor does it mean giving a moral lecture. It means spreading the news.

freedom - - (CW) "Freedom" is the noun that means "letting go," "release," "relaxation," "exhaustion," "liberty," "exemption from attendance," "leave of absence," "divorce," and "the beginning [of anything]." It is the noun form of the word usually translated as "forgive" in the NT that has a meaning closer to "let go." This is not the word usually translated as "freedom."

for -- This word "for" comes from the dative case of the following word that requires the addition of a preposition in English. The most common is a "to" for the English indirect object.

the -- (IW) There is nothing that can be translated as "the" in the Greek source. 

prisoners , The Greek word translated as "prisoners " means  "captive" and "prisoner." It is an adjective, used as a noun. When Christ does this, he usually uses an article ("the"), but the OT Septuagint does so less often because the article is not used in the original Hebrew. This word is uncommon for Christ to use. 

and -- The Greek word translated as "and" is used as the conjunction "and," but it also is used to add emphasis ("also"). In a series, it can be translated as "not only...but also." After words implying sameness "as."

recovering of sight  - The Greek word translated as "recovering of sight" is not a verb but a noun meaning "seeing again."

However, the translator can choose other prepositions: "with,"  "in,"   "of,"  "as," "by," "for," "at," or "on" depending on the context. The case can indicate a "with" for instruments, an "in" for locations, an "for" for purposes, an "about" (or "for" or "against") indicating interest, an "of" for possession, a "by" for agents, an "as" for comparisons, "at" or "on" a time, and an "in" for area of effect. -

the -- (IW) There is nothing that can be translated as "the" in the Greek source. 

blind, -- "Blind" is a word that means both physically and mentally blind. It also means all things that are obscure. It has no article "the" before it.

to -- This "to" is added because the infinitive form of the verb requires a "to" in English. This verb could be an infinitive but "to send out" doesn't work will, so the translators changed it. The verb form that works better here is the rare one (the optative) that has the meaning of something desired on the part of the speaker. In this case, it would mean, "I wish he would send out." This perfectly fits something a person would add instead of reading from a text.

set --- (WW) The "set" here is a word that means "to send off" and "dispatch." It is the source of our word "apostle." This word is not the simple "send" but a more complex one that means "send out" or "send from."

liberty - - (CW,WP)  "Liberty" is the noun that means "letting go," "release," "relaxation," "exhaustion," "liberty," "exemption from attendance," "leave of absence," "divorce," and "the beginning [of anything]." It is the noun form of the word usually translated as "forgive" in the NT that has a meaning closer to "let go." This is the same Greek word translated as "deliverance" earlier in the verse. The "liberty" doesn't belong here but before after oppressed.

the  - -There is no Greek article "the" here in the source, but the participle is plural and in English, a definite article "the/this/that/theses/those" is used before plural verbal nouns in phrases like this. This is not the word usually translated as "them."

oppressed ,  - (CW, WT, WV) "Oppressed" is the Greek verb, that means "to break in pieces", "shatter", "break down", and "enfeeble." It is in the adjective form of "having been broken ". The voice is passive and the tense is past perfect.

missing "in "  -- (MW) The untranslated word "in" means "in," "within," "with" (an instrument), "by" (near), "by" (means of), "during" (time),  or "among"  with a dative object as the one here.  With the accusative, it means "into," "on," and "for."
