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." 

John --  "John" is the Greek word translated as the English proper name. 

the -- The word translated as "the" is the Greek definite article, "the," which usually precedes a noun. Without a noun, it has the sense of "the one." Before an adjective or a particle, it changes the following word 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. 

Baptist  - The Greek word translated as "baptize" means "to dip," "to plunge," "to be drenched," "to be drowned," and "getting in deep water." It is in the form of an adjective, baptizing."

came -- The word translated as "came" 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.

neither -- (CW) The negative used here is the Greek negative of a subjective opinion, commands, verbs of possibility, and requests. Used with verbs in the mood of possibility to express a prohibition. It is used with verbs of subjective action--thinking, feeling, seeing, etc. When used with verbs of physical action, its sense is that "not wanting" or "thinking" something, not that it isn't done or thought.  With these verbs, the sense is "rejecting" the action, rather than simply not doing it.

eating -- The word translated as "ye shall eat" means "eat" but it also means "fret," as we say "something is eating me up."

bread -- The word translated as "bread" means "small loaf or cake of bread." It is more like a slice of bread today. It describes a thin 1/2 inch thick round or an oblong loaf of wheat bread, meant to be torn into pieces and not cut. It was closer to a flour tortilla or a piece of pan than a loaf of bread. "Bread" is one of Christ's most basic symbols, representing temporary physical nourishment as contrasted with permanent spiritual nourishment.

nor --    (CW)This Greek word translated as "nor" means "neither," "nor,"and not." It is used mostly double as a "neither...nor."  The negative is the negative of opinion, not fact. 

drinking -- The word "drink" is the Greek for meaning to "drink." It also has a double meaning. "To drink" also means "to celebrate."

wine; -- The word translated as "wine" means "wine" or any fermented juice. Wine, however, is Christ's metaphor for mental thought, the drink affecting the mind.

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."

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

For John the Baptist came neither eating bread nor drinking wine, and say, ‘He has a .’

say,   -- The word translated as "ye say" is the most common word that means "to say," "to tell," and "to speak,"  but when used with an objective noun or pronoun, the sense is "say of" or "speak of."  When two accusative objects are used, the sense is  "say of him this," or "call him this." The form Jesus uses to describe his own speaking can be either indicative, "I say/tell" or subjunctive, "I should/could say/tell."  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."."

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

has-- The word translated as "has" means to "have," "possess," "bear," "keep close," "hold in," "to have due to one," or "keep" and many specific uses. When its object is an infinitive verb, it means "it could," not "in must" as in English.  This verb isn't used to form past tenses as the helper verb does in English. Nor does it have the sense of "must" when used with infinitives.

a -- There is no indefinite article in Greek, but when a noun doesn't have a definite article, the indefinite article can be added in English translation.

demon. --  (CW) "Demon" is a word that means "belonging to a controlling spiritual power" so the sense is "an invisible controller." The word doesn't necessarily mean "evil". In Greek is used to refer to a controlling spiritual power, inferior to the gods. It was used to mean "knowing" and "skilled" in the sense that we might say, "He is a demon poker player." However, Jesus seems to always use it negatively as "an unseen controller" referring to   invisible causes of disease, especially mental disorders (see this article). In English, our word "daemon" retains these same meanings when it isn't used as an alternate spelling of "demon."
