For parents

Can is can means: While something is possible or makes sense in theory, it may not be as straightforward or sensible as initially thought, or may prove to be less successful in practice.. It has drug-related associations; worth a calm conversation about which side of the topic your teen is on. If your teen uses it, context will usually make the intent clear. A short, curious question about where they heard it is usually all that is needed to know whether to follow up.

For ESL learners

can is can means: While something is possible or makes sense in theory, it may not be as straightforward or sensible as initially thought, or may prove to be less successful in practice.. Register: very informal, often derogatory or vulgar. Avoid in formal, business, academic, or polite writing. Even in casual speech the word can offend and is best left out of a learner's active vocabulary. A common learner mistake is using the word in a register it does not fit, or assuming a single global meaning; native speakers immediately notice when slang appears in formal contexts, so always check the surrounding register before producing it yourself.

Why is this section here?

Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
