And-- (WW) The Greek word for "neither" is an adverb that means "not at all" or "no even." As a conjunction, it works as both parts of the "neither/nor" constructions.  The previous verse had a neither/nor construction and this seems to continue it, except for the next word, which is untranslated in the KJV. This word doesn't mean "and."  

missing "because"  -- (MW) The untranslated word  introduces a reason or explanation so "because" and, in questions, "why."  However, since this word always appears in the second position, it is more like an aside remark like, "consequently" or "as a cause." 

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

can -- (CW, WV) The word translated as "can" means having the power or possibly a desire to accomplish something. Often, in English, "can" is a helper verb, indicating a possibility. In Greek, it indicates ability or power. This is the active verb here, not a helper verb. It takes an infinitive as "have the ability" does in English. In English, "can" is a helper verb, indicating a possibility. See this article. 

 no longer  -- " No longer" is an adverb that means "yet" and "still," "already,"  "longer," "no longer" (with a negative), "still" and "besides."  The sense is "no longer." This is one of those situations where a single Greek negative requires two negatives in English.

die -- (WF) "Die" is a Greek verb that means "to die" and "to die off," but it's form is an infinitive "to die." This form goes with the verb "can," which really has the sense of "have the power to die." 

 any more -- "Any more" is an adverb that means "yet" and "still," "already,"  "longer," "no longer" (with a negative), "still" and "besides."  The sense is "no longer." This is one of those situations where a single Greek negative requires two negatives in English.

for -- The word translated as "for" introduces a reason or explanation so "because" and, in questions, "why."  However, since this word always appears in the second position, it is more like an aside remark like, "consequently" or "as a cause."  This was the word untranslated in the previous verse.

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

are -- The verb "are" here is the common form of "to be" in Greek. It means to have a certain characteristic or remain in a certain condition. It also equates terms or assigns characteristics.

 like the angels  -- "Equal unto the angels" is an invented word, appearing only once in ancient Greek, here in the Gospels. It means "like an angel." It is created from isos, which means "equal" in size, strength, number, or rights and aggelos, which means "messenger" and "envoys." This phrase actually appears in previous clause, not in this one. We know this because the position of the "for" (see above) indicates the start of the clause.

missing "and "  -- (MW) The untranslated word "and" is used as the conjunction "and," but it also is used to add emphasis ("also"). In a series, it is can be translated as "not only...but also." After words implying sameness "as." Because of its position in the verse a "also" or "as" works better because the word doesn't join words, phrases, or clauses in any clear way.

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

are -- The verb "are" here is the common form of "to be" in Greek. It means to have a certain characteristic or remain in a certain condition. It also equates terms or assigns characteristics. The form is the same as above, but the verb comes before the "and" so these verbs are not joined that conjunction. This word starts a new clause, "they are."

God -- The word translated as "God" means "God" and "deity." It is not introduced by an article, which is how Jesus used it when referring to the one God. Instead, this has the sense of "divinity."

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

children -- The word translated as "children" means "son" and more generally "child" or "children." It can refer to all offspring in later generations, just like "father" refers to all previous generations. More about it in this article. It is not introduced by an article so "children" not "the children"

 since they ---- (IP) There is nothing that can be translated as this phrase in the Greek source.

are -- (WF) The verb "being here is the common form of "to be" in Greek, but the form is that of an adjective modifying "children" below, so "existing" or "being" or "existent." 

children -- The word translated as "children" means "son" and more generally "child" or "children." It can refer to all offspring in later generations, just like "father" refers to all previous generations. More about it in this article. It is not introduced by an article so "children" not "the children"

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

the -- The word translated as "the" is the Greek definite article, "the," which usually precedes a noun or changes the word it precedes (adjective, infinitive, participle, etc.) to act like a noun. The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those") than the English "the." See this article for more. 

resurrection --. (CW) While the Greek word translated as "resurrection" is understood that way today, during Christ's time, it would have meant simply "a rising up" or "awakening." It was used to indicate someone standing up especially when awakening from sleep. The word "resurrection" has a religious meaning that the Greek word didn't have.
