Again, this verse look much more like an answer to a question. It works verbally much better than a written statement. The beginning "they will say" seems to repeat part of the question. Again, the effect is largely humorous.

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. 

"Shall they say" is from the Greek verb that means "to say" and "to speak" also.

"Lo" is a verb meaning "Behold!"  and "See there!" Ii is also an adverbial introducing a reveal like  we use the phrase "tah-dah" in a magic show, or the French "voila". In a humorous vein, Jesus uses this like word both ways, like  "Look!" or "Tah-dah!".  This first use is more like "See!" It is a form of the common verb that means "to see" or "to perceive."

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

"Or" is translated from a Greek word that means primarily "or" but serves as "than" in a comparison.

"Lo" is the same verb/adv described above, but it doesn't exist here. The word is used later in the sentence. This "lo" is added.

"There" is a word meaning "there", "in that place," and in philosophy means "the intelligible world." It follows the "or" so "Look here or there!".

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 in the phrase, it is more like an aside remark like, "as an explanation" or "as a cause". 

"Behold" is a verb meaning "Behold!"  and "See there!" It is also an adverbial exclamation introducing a reveal like  we use the phrase "tah-dah" in a magic show, or the French "voila". In a humorous vein, Jesus uses this like word both ways, like  "Look!" or "Tah-dah!".  This second use is more like the adverb, "Tah-Dah!"

The word translated as "the 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.

The word translated as "of God" means "God" and "deity." It is introduced with an article, so "the God." Jesus often uses it this way perhaps to indicate the one God as opposed to the pagan gods. The :"of" comes from the possessive form.

The verb "is" 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. It ends the sentence.

The "within" is not a reposition, but adverb but Jesus uses it like a noun. As in English, this word had the sense of "insider" and "being special" in contrast to "outsider" and "being common."

The word translated as "your" is plural addressing a group of Jesus's listeners so the sense is "inside of you all".
