Woe -- "Woe" is an exclamation of grief, meaning "woe" or "alas." Jesus uses it humorously. Today we would say "so sad for you" or "boo-hoo to you." The word is very like the Jewish, "oy vey" which can be used to express sorrow but is more commonly used cynically. More about this phrase in this article on Christ's humor using exaggeration.

unto -- 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. However, the translator can choose other prepositions: "with,"  "in,"   "of,"  "as," "by," "for," "at," or "on" depending on the context.

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

that  -- (WN) The word translated as "that" is the Greek definite article, "the," which usually precedes a noun. Without a noun, it has the sense of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those") than the English "the." See this article for more.  This word is not singular but plural.

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

full! - (WF ) The Greek verse translated as "that are full" means to "fill quite full",  "fill full of" a thing, and, in the passive, "to be satiated." This is not the word translated as "shall be filled" in Luke 6:21 or Matthew 5:6. That word is used as a punchline, having the sense of "get your fill". This word is also a punchline but has the sense of being stuffed. This is the only time Jesus uses it. The tense of the verb is something completed in the past, not the present tense, as shown, and the form is something people do to themselves, "having stuffed themselves". This word is a participle, not an adjective. It is the past perfect tense and the middle voice.

missing "by/for yourselves"-- (WV) A phrase is necessary because the form of the previous verb is a middle voice, which means that the subject is to  act on "yourselves," "for yourselves" or "by yourselves."

missing "now" - (MW) The untranslated word    "now" means "now," "at the present moment,""presently," and "as it is." With the article, its sense is "the present" or "this now."

for -- The word translated as "for" introduces a statement of fact or cause, "for what," "because," "since," and "wherefore." Jesus usually uses this word to mean "because" in statements that seem like an answer to a question because of the change of context.

ye -- This is from the second-person, plural form of the verb.

shall -- This helping verb "shall" indicates that the verb is the future tense or a form that indicates possibility at some time. A "might" or "should" could work here or nothing at all in an "if/when/whoever" clause which implies a possibility.  Helping or auxiliary verbs are needed to translate the Greek verb forms into English.

hunger. - The word for "hunger" is the verb for "to hunger" as in needing food and, like the English word, it is a metaphor for any craving. It is in a form that could be the future tense or the subjunctive mood. This means either "will starve" or "might starve".

Woe -- "Woe" is an exclamation of grief, meaning "woe" or "alas." Jesus uses it humorously. Today we would say "so sad for you" or "boo-hoo to you." The word is very like the Jewish, "oy vey" which can be used to express sorrow but is more commonly used cynically. More about this phrase in this article on Christ's humor using exaggeration.

unto you  - -- (OS) There is nothing in the Greek that can be translated as "unto you" in the source we use today but it does exist in the source that the KJV translators used.

that  -- (WN) The word translated as "that" is the Greek definite article, "the," which usually precedes a noun. Without a noun, it has the sense of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those") than the English "the." See this article for more.  This word is not singular but plural.

laugh - (WF) The verb translated as "laugh" means "to laugh" but it covers not just happy laughter. It includes laughing at people and deriding them. Its use is entertaining because so much of what Jesus said was designed to make people hearing him laugh. Some of the humor was even used to deride others in a light-hearted way.  This word is a participle, not an active verb.

now!  -- The Greek word translated as "henceforth" means "now," "at the present moment,""presently," and "as it is." With the article, its sense is "the present" or "this now."

for -- The word translated as "for" introduces a statement of fact or cause, "for what," "because," "since," and "wherefore." Jesus usually uses this word to mean "because" in statements that seem like an answer to a question because of the change of context.

ye -- This is from the second-person, plural form of the verb.

shall -- This helping verb "shall" indicates that the verb is the future tense or a form that indicates possibility at some time. A "might" or "should" could work here or nothing at all in an "if/when/whoever" clause which implies a possibility.  Helping or auxiliary verbs are needed to translate the Greek verb forms into English.

mourn  - "Mourn" is a Greek word that means "to bewail," "to mourn," "to go mourning" and "to lament." It is the same word used for "mourn" in the Beatitudes (Matthew 5:4).

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

weep. - The verb translated as "weep" means "to weep", "to lament," and "to cry".
