These are the first words the risen Jesus speaks in Luke to two followers walking outside of Jerusalem. Almost every word in the KJV is translated in an uncommon way. Other Bibles take even more liberties. There is one unique word here for Jesus, but it is just the kind of funny word that he would use. The last three words seem to describe the reaction of the followers to the question. It doesn't seem part of the quote.

The word translated as "what" means primarily "anything" or "anyone," but Jesus often uses it to start a question so it means "who", "what", or even "why". 

"manner of communications" is translated from a Greek word that means "calculation," or "reasoning." It is the source of our word "logic" and is the root word for all the English words that end in "-ology." Most biblical translations translated it as  commonly "word" for somewhat poetic reasons. More about this word in this article. In English, we would say "idea" to describe it. 

There is no "are" here, but in Greek nouns in the form of a subject can be used like this with the "are" assumed.

"These" is translated from a Greek word that means "this", "that", "the nearer."

The word translated as "that" is a demonstrative pronoun ("this" "that"), but it often acts as a pronoun ("the one that), especially a connective pronoun ("the one that") introducing a dependent clause.

"Ye have" is not the Greek word "have" or anything like it. It is a word that Jesus uses only here in the NT. It means which means "throw against," "throw in turn," "put against each other," "exchange words "(in a conversation), and "compare". The obvious meanings is "to exchange words" but the sense is lighter, like the literal meaning which is "toss against" or "toss mutually". In English, we would say "toss back and forth."

The "one...another" here is an uncommon word for Christ, and primarily it means "one another." Here, it appears before the verb.

The word translated as "to" means "towards", "by reason of (for)," and "against."

There is no "as" in the Greek.

There is no pronoun "ye" here and the verb is not in a second person form.

"Walk" is a Greek verb that means "to walk up and down", "to walk about," and "to walk about while teaching." The form of that of an adjective, "walking about". The form is masculine plural.

It isn't clear to me that these last three words, "and are sad" are part of the quote.  To me, they read more like a description of the two followers reacting to the question. The verb is not in the second person, which you would expect nor does the tense make any sense in a quote.

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

The verb translated as "are" means "to make stand", "to set up", "to establish and similar words. Like the English words "put" and "set," it has a number of specific meanings including a passive one that means "behave" or "take up an attitude. However, in the passive it can also be a stronger form of "to be" when referring to being in a certain state, maybe "they are being". The tense is something happening at a specific point in time, past, present, or future. This tense only makes sense if describing there two followers reacting to the question.

The Greek word translated as "sad" is an adjective that literally means "a sullen look."
