You are already clean the word I have spoken to you.

You  -- The pronoun "you" 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.

missing "yourselves"  ---- (MW) The pronoun is used here explicitly as the subject of the sentence. Since this information is already in the verb, the sense is repetitive as we say "you yourselves."

are -- The verb "are" 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.

already --  "Already " is a Greek adverb meaning "by this time," "forthwith," "after," "immediately," and "now." It means proximity in time, but also place.

clean -- The Greek word translated as "clean" means "physically clean," "spotless," "free of contamination," "clear of debt," "genuine," "pure of birth," "without blemish," and "sound."

because of -- The preposition translated as "for...reason" means with the accusative used here, means "thanks to," "because of,"  "by reasons of," and "for the sake of."

the -- The word translated as "the" is the Greek definite article; 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.

word -- (CW) "Word" is translated from a Greek word that means "calculation," or "reasoning," but it has many, many specific meanings from "deliberation" to "narrative."  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 "word" for somewhat poetic reasons. However, when applied to people, it means "repute" or "reputation." More about this word in this article. In English, we would say "idea" to describe it but it also means the communication of various types, so "message" often works better.

missing "which"  -- (MW) The untranslated word "which" is a demonstrative pronoun ("this" "that"), but it often acts as a pronoun "which," "what," "who," "whosoever," "where," "for which reason," and many similar meanings.

I -- This is from the first-person, singular form of the verb.

have -- This helping verb "have" indicates that the verb is the tense indicating an action completed in the past.

spoken -- (CW) The Greek word translated as "speak" is not the ordinary "to say," "to talk," "to tell," or "to speak" in Greek. This word means "idle chatter," "gossip," and "the proclamations of an oracle." Jesus uses it to capture the idea of "passing on." "conveying,"  or "relaying" information.  When there isn't an object, "transmit" captures the idea of being a conduit rather than a source of information.

unto to -- 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.

you.  -- The Greek pronoun "you" here is plural and in the form of an indirect object, "to you," "for you," etc. As the object of a preposition, this form implies no movement, but in a fixed position or events occur at a specified time or while the action was being performed.
