Young man,  "Young man" is an uncommon word for "youth", and "young man." The word translated  as "young man" means "youth", and "young man." This is the only time Jesus uses this word. 

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

say -- The word translated as "I tell" is the most common word that means "to say," "to tell," and "to speak,"  but when used with an objective noun or pronoun, the sense is "say of" or "speak of."  When two accusative objects are used, the sense is  "say of him this," or "call him this." The form Jesus uses to describe his own speaking can be either indicative, "I say/tell" or subjunctive, "I should/could say/tell."  It also has many ancillary meanings such as "to count" ("to number" or like we might say, "to recount" a story) or "to choose for yourself."

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 word for "you" is the indirect object form of the singular, second-person pronoun in the form of an indirect object, which usually requires a preposition in English, like "to you."

get up -- (CW, WV) The word for "get up" means "awaken" and is the same word Jesus uses to describe God raising the dead and false prophets arising. We use our phrase "get up" to mean "wake up," but it is also used simply to tell people to stand up. While this primary meaning is “awaken," “rouse,” or “stir up,” in various forms and, in different contexts, it means “wake up,” “stay awake,” and “to be awake.” It can also mean “to stir yourself,” “excite yourself,” or to “be excited” by passion.” It also forms various idioms. For example, when used with “ears” it means “prick up your ears.” It also means “raise” or “erect,” but usually in the context of constructing buildings. It is only consistently translated as “raise” in the NT and later works based on it. The verb here is translated as the active voice but it is passive.
