Quick Reference

Meaning & Definition

使える (tsukaeru) is the potential form of 使う (tsukau), meaning “to be able to use” something — but in everyday speech, it doubles as a punchy expression of approval: 「使える！」means “That works!” or “That’s a real find!” when someone shares a clever tip or trick.

As the potential form of 使う (tsukau, “to use”), 使える literally asks whether something can be used or is still functional. “このアプリ、使える？” means “Does this app work?” or “Is this app any good?” In casual conversation, 「使える！」 stands alone as a compact compliment meaning “That’s useful!” or “Good call!” — the subject (the idea, tool, or tip being praised) is dropped entirely, as is typical in colloquial Japanese. In formal contexts, the honorific form ご使用いただけます (go-shiyō itadakemasu) replaces 使えます to add politeness. Note the homophone 仕える (tsukaeru), which means “to serve” or “to work under someone” — distinguished only by kanji and context, never by sound.

How to Use It

Learners sometimes confuse 使える with 使う: 使う is the plain action (“I use”), while 使える is the potential (“I can use” / “it can be used”). When 使える describes an object — “このペン、使える”— it often means the object is still functional or in working order, not that the speaker has permission to use it. For permission, Japanese speakers typically use 使っていい (tsukatte ii) or 使えますか as a polite question. Also watch the homophone 仕える (tsukaeru, “to serve”): in speech they are identical, so rely on context and kanji when reading.

Kanji Breakdown

The kanji 使 combines イ (the person radical, a simplified form of 人) on the left with 吏 (ri) on the right. 吏 depicts an official who carries out orders — someone who acts under instruction. Together, 使 captures the idea of a person who is directed to act, giving rise to meanings like “to use,” “to send on an errand” (使い, tsukai), and “to employ.” This root explains why 使える covers both the physical act of operating something and the figurative sense of putting something to productive use.

Example Sentences

Cultural Context

In Japanese workplaces, 使える人材 (tsukaeru jinzai) — literally “usable talent” — is a frank, pragmatic compliment for someone who gets things done without hand-holding. While the phrasing can sound blunt to outsiders, it reflects a results-oriented professional culture where practical competence is prized. Calling a colleague 使える is a genuine sign of respect in many office environments.

Outside the office, 使えるワザ (tsukaeru waza, “tricks that actually work”) is a staple phrase in Japanese lifestyle content — from budget cooking channels to DIY home repair guides. The framing signals that the tip has been tested and proven, not just theoretical. This usage turns 使える into a quality stamp: if something earns the label, it is worth keeping in your repertoire.
