deru
= to leave; to exit; to go out; to appear; to come out; to answer (phone)
Deru (出る) covers an unusually wide range of actions — from physically leaving a building to appearing on television to answering a ringing phone — all with the same word. Mastering its range unlocks dozens of everyday situations at once.
At its core, deru describes something or someone moving from an interior space to the outside: ie wo deru (leave the house), eki wo deru (exit the station). From there the verb expands outward. It covers making an appearance — terebi ni deru means to appear on TV, not just to walk past one. It also describes things emerging or being produced: koohii ga deru (coffee comes out / is served), kotae ga deru (an answer comes out / emerges). In telephone contexts, denwa ni deru is the standard phrase for answering a call, equivalent to English “pick up” or “answer the phone.” Because deru is intransitive, the thing that exits is always the grammatical subject marked with ga or the place exited is marked with wo — the verb itself takes no direct object.
The most important pair to learn alongside deru is dasu (出す), its transitive counterpart. Deru is intransitive — the subject moves or appears on its own: mizu ga deru (water comes out). Dasu is transitive — someone actively brings something out: mizu wo dasu (turn on the water / put out water). Mixing them up is one of the most common errors at N4 level. A quick test: if you can ask “who did it to what?”, you need dasu; if the thing just happens by itself, use deru. Also note that denwa ni deru uses the particle ni, not wo — you are responding to the phone, not exiting it.
The character 出 is one of the oldest pictographs in Chinese and Japanese writing. Oracle-bone inscriptions show two overlapping mountain peaks, representing something rising above a ridge and coming out into the open. Later forms stylized this into the modern two-tiered shape: a smaller peak sitting atop a larger one, both pointing upward. The core image — emergence, coming forth — runs through every usage of deru today, whether a person exits a door or a result surfaces from a process.

Denwa ni deru — answering the phone — is a phrase every Japanese learner encounters quickly, yet its grammar surprises English speakers. In English you “answer” or “pick up” the phone (transitive). In Japanese, deru is intransitive: you go out to meet the call, rather than acting upon it. This reflects a broader Japanese tendency to frame responses as movement toward something rather than as direct actions.
The intransitive/transitive pair deru / dasu is part of a grammatical pattern that appears throughout Japanese: akeru (to open, transitive) vs aku (to open, intransitive); ireru (to put in) vs hairu (to enter). Learning deru and dasu together gives learners a template for understanding this wider self-move vs caused-move distinction, which native speakers apply automatically and which shows up on the JLPT N4 grammar section.
