“sent” vs. “cent”
Use "sent" as the past tense of "send" (a verb); use "cent" for the monetary unit worth one-hundredth of a dollar (a noun).
sent
"Sent" functions as both the simple past tense and the past participle of "to send," describing the act of causing something to go somewhere ("she sent the letter," "he had sent the package last week"). It's an irregular verb form, following the same vowel-shift pattern as "bend/bent" and "spend/spent" rather than adding a regular "-ed" ending. "Sent" also appears in a range of fixed expressions, such as "sent packing" (dismissed abruptly) and "sent for" (summoned), both of which preserve the core meaning of causing movement or communication, just applied idiomatically rather than literally to letters or packages.
cent
"Cent" is a noun for a monetary unit equal to one-hundredth of a dollar (or similarly divided currencies in other countries), and comes from Latin "centum," meaning "hundred" — the same root that gives us "century," "centipede," and "percent." A single coin worth one cent is commonly called a "penny" in casual American speech, but "cent" is the formal term for the unit of currency itself.
The real distinction
"Sent" is a verb describing a completed act of sending; "cent" is a noun naming a small unit of money, and the two share only their sound, never their grammar or meaning. Because "sent" always needs a subject that performed the sending and typically an object that was sent ("she sent flowers"), while "cent" always attaches to a number or currency context ("fifty cents," "a one-cent stamp"), the sentence structure alone usually prevents any real confusion. The error that does occur tends to happen in fast typing or among English learners still building intuition for irregular past-tense verbs, occasionally writing "cent" where "sent" was intended, especially in phrases involving mail or money together, such as historical references to letters sent for a one-cent stamp. One more small but reliable check: "sent" will always be replaceable with another past-tense verb like "mailed" or "delivered," while "cent" will always be replaceable with a specific number of money, such as "penny" or "dollar fraction" — running that substitution test mentally is often faster than trying to reason through the grammar from scratch.

Memory trick
"Sent" belongs with other irregular "-ent" past tenses like "spent" and "bent" — verbs about something happening and finishing. "Cent" belongs with money words built on the Latin "centum" (hundred), like "century" and "percent" — a family of words all rooted in counting. As a final check, try reading the sentence aloud substituting "mailed" for the word in question — if it still makes sense, you need "sent"; if instead "penny" fits better, you need "cent."
