と – And (Listing Nouns) / If・When (Natural Consequence)

JLPT N5ParticleNeutral
The particle has two primary functions at the introductory level. First, it works as a noun-linking particle meaning "and," connecting two or more nouns in an exhaustive list — meaning you are listing all the items, not just some. This differs from , which implies a non-exhaustive, partial list. Second, functions as a conditional conjunction meaning "if" or "when," describing outcomes that are natural, automatic, habitual, or inevitable. When used conditionally, the result in the second clause is something that always or naturally follows from the first clause — such as natural phenomena, machine operations, or habitual routines. This conditional use differs from たら and , which can express hypothetical or one-time conditions more freely. Because implies a guaranteed or predictable result, it is generally not used with requests, commands, invitations, or expressions of personal will in the second clause.

Structure
Noun A + と + Noun B
かばんのなかにペンノートがあります。

There is a pen and a notebook in the bag.

Here connects the nouns ペン and ノート to form a complete, exhaustive list of what is in the bag. Unlike , which would suggest there might be other items too, implies that these are all the items being mentioned. You can chain more than two nouns by placing between each pair.

Common mistakes

A very common mistake is using to connect adjectives or sentences instead of nouns; remember that the listing function of only links nouns, not clauses or adjectives. For connecting adjectives or clauses, use the て-form or instead. Another frequent error is using the conditional when the result clause contains a request, command, or expression of will (such as てください or たい), which is ungrammatical because implies an automatic or natural outcome, not something the speaker is asking for. Learners also sometimes confuse with when listing nouns: gives a complete list while gives a partial one, so choosing the wrong particle changes the meaning. Finally, when using the conditional , the verb before it must be in the plain (dictionary or ない) form — attaching after ます-form is incorrect.
