Verily -- The word translated as "verily" is from the Hebrew word that means "truly" or "certainly," but it sounds like the Greek word with the same meaning. In Greek, the word also means "to reap." See this article discussing this "amen phrase."

I -- This is from the first-person, singular form of the following verb.

say -- The word translated as "say" is the most common word that means "to say," and "to speak," but it also means "to teach," which seems to be the way Christ uses it more frequently. It also has many ancillary meanings such as "to count" ("to number" or like we might say, "to recount" a story) or "to choose for yourself." Christ usually uses this word to refer to his own speaking or teaching.

unto -- This word "unto" comes from the dative case of the following word that requires the addition of a preposition in English, but the translator must decide which preposition to use: a "to" as an indirect object.

you,  -- The Greek pronoun "you" here is plural and in the form of an indirect object, "to you," "for you," etc.

missing "that"  -- (OS) The untranslated word is "that" here in the sources we use today and it introduces a statement of fact or cause.

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

be -- (WN) When the verb "to be" appears early in the clause before the subject, the sense is more like "it is" or, in the plural, "there are." It is plural so "are."

some  - The Greek word translated as "some" is the plural version "anyone," "someone," and "anything." In the plural, it means "some," "they," and "those."

missing "of those"  -- (MW) The untranslated word is the Greek definite article, which usually precedes a noun and, without a noun, takes the meaning of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those"). See this article for more. It is plural, possessive so "of those."

standing  - (WT) "Standing" is the noun form of the verb which means "to make a stand," "to set up," "to place," or "to stand." It is plural and the tense indicates an action completed in the past so "having stood."

here, - The word translated as "here" means in manner, "in this way," referring to the manner, or "here," referring to place.

which -- "Which" is a pronoun that means "that," "anyone who," "anything which," "whosoever," "whichsoever" and "anybody whatsoever." 

shall  -- (CW) This helping verb "shall" does not indicate the future tense, but that the verb describes a possibility, the subjunctive voice. A "might" or "should" in English is more appropriate,

not  - (CW) The "not" here is both of the Greek negatives used together. Greek has two negatives, one objective, one subjective. The use of both together is more extreme, like saying "you cannot really think." It is often translated as "never." 

taste  - "Taste" is a verb that means "to taste," "to feel," and "to experience." It is not in the future tense, but a form that is usually translated as the past tense but which means something happening at some specific point in time. It is a middle form, something people can only do for themselves.

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

death,  - "Death" is from the Greek word meaning "death" generally and the death penalty specifically. Jesus only uses this word fifteen times.

till  - The word translated as "till" means "until" but it also means "in order that."

missing "when"  -- (MW) The untranslated word "if might" indicates more of an expectation of something happening than "if" alone. This is often how we use the word "when" as a conjunction.

they  - -- This is from the third-person, plural form of the verb.

see  - The verb translated as "they see" means "to see" but it is used like we use the word "see" to mean "to know" or "to perceive." In th KJV, it is almost translated as many times as "know" as it is "see,"

the -- The word translated as "the" is the Greek definite article. The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those"). See this article for more. 

Son -- The word translated as "son" more generally means "child" or "descendant." The phrase "the son of man" is the common way Christ refers to himself. It is discussed in detail in this article. Its sense may be "the child of the man."

of -- This word "of"  comes from the genitive case of the following word that required the addition of a preposition in English.  The most common is the "of" of possession, but it can also mean "belonging to," "part of," "which is," "than" (in comparisons), or  "for," "concerning" or "about" with transitive verbs. 

missing "the"  -- (MW) The untranslated word is the Greek definite article, which usually precedes a noun and, without a noun, takes the meaning of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those"). See this article for more. 

man - The Greek word for "man" means "man," "person" and "humanity" in the singular. In the plural, it means "men," "people," and "peoples." 

coming -- The word translated as "coming" primarily means "to start out" but Christ usually uses it to mean "come" but not always. It indicates movement, especially its beginning, without indicating a direction toward or away from anything, so it works either as "start," "come," or "go," but it is more like our phrase "being underway." Our English word "show up" captures both the "start" and "come" ideas. See this article for more.

in -- The word translated as "in" means "in," "within," "with," "during" (time),  or "among"  with a dative object as the "kingdom" here.  It does not mean "into" indicating movement, which requires a different form of an object.

his  - -- The word translated as "his" is the Greek word commonly translated as third-person pronouns in English.  This pronoun follows the noun so "of his."

missing "the"  -- (MW) The untranslated word is the Greek definite article, which usually precedes a noun and, without a noun, takes the meaning of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those"). See this article for more. 

kingdom.  -- The word translated as "kingdom" can be the region, the reign, the castle or the authority of a ruler. Christ does not seem to use it to mean a physical region, so its translation as "reign" or "realm" seems more appropriate. This is especially true because the "reign" of a king means the execution of his will. More about this term in this article.
