If -- The "if" here expresses a condition but it means nothing regarding whether that condition is met or not when used with the subjective negative. It also means "if ever" and "whenever." However, when used in an "if" clause, the verb is the subjunctive form of possibility. When citing a fact with a declarative verb, indicative, instead of one of possibility with the objective negative, the sense is more "since" or "as sure as." When this word is paired with the conjunction translated as "but" or "however," the structure works like an "if then" statement in English. With an imperative, it is used to express a wish. The sense is "I wish that."

any -- The Greek word translated as "any" in the singular means "anyone," "someone,"  "something," and "anything." The same forms are used both for the masculine or feminine so "anyone" works best for a person. In the plural, it means "everyone," "some," "they," and "those." Jesus often uses it to start a question so it means "who," "what," or even "why."

man -- (IW) There is nothing that can be translated as "man" in the Greek source. The form is singular and can be either masculine or feminine.

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

ears -- The term translated as "ears" means "ear," things resembling a handle and is a metaphor for understanding.

to This comes from the infinitive form of the following verb.

hear, -- "Hear" is from a Greek verb that means "to hear" and "to listen." It has the same sense as the English not only of listening but of understanding.   It also means "to listen" and "to understand," but amusingly, it also means "to be silent." The accusative object is the person/thing heard about, while the genitive is the person/thing heard from.  However, two genitives can be used with the sense of "hear of a thing from a person."

let  - (CW) This word is added to translate the third-person command form of this word but this makes it a second person command. In English, we would probably use "must." This is not the common word that means "let."

him  - (WF) This comes from the singular form of the verb, but it is a subject not an object.

hear. -- "Hear" is translated from a Greek word that has the same sense as the English not only of listening but of understanding.
