This verse stands out from the similar verses in Matthew and Mark because it does not mention a "door" at the end as they do. It copies some of the  uncommon structures in Luke 21:28. However, this verse uses no uncommon words, which is unusual for this section of Luke.

"So " is translated from a Greek word that in its adverbial form, so it means "in this manner" or "in this way."

The Greek word translated as "likewise" is used as the conjunction "and", but it also is used to add emphasis ("also"). After words implying sameness "as".

, The pronoun "ye" is used explicitly as the subject of the sentence. Since it is already part of the verb, its use here creates emphasis on the "you" as we might say "you yourselves." It is plural.

The Greek word translated as "when" introduces a phrase that explains a certain condition so "whenever" or "since."

The verb translated as "ye see" means "to see" but it is used like we use the word "see" to mean "to know" or "to perceive." The form is that of something that might happen.

The "these things" is a pronoun that can mean "this" or "that," the nearer or the further depending on usage. As an adverb it can mean "therefore" and "that is why." It is not typically used as an adjective.

The word translated as "to come to pass" means "to become," or, of events, "to happen",  that is, to enter into a new state. Though this is the infinitive of the verb, "to happen", it acts as the subject of a sentence. Infinitives introduced by an article, or in this case, a related adjective, act as a noun describing the verb's action. So "to happen" becomes "these happenings", following the plural form of the adjective. This is the same construction as we saw in Luke 21:28.

The word translated as "know ye" means literally, "on learning to know" or "by learning to know." Generally, it means "to witness" or "to discover."

The word translated as "that" introduces a statement of fact or cause.

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.

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 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. -- When the verb "to be" appears early in the sentence before the subject, the sense is more like "it is" or, in the plural, "there are." 

The adverb translated as "nigh at hand" means near in time or distance.
