A house habitually kept open to callers.

For parents

Open house means: A house habitually kept open to callers.. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. 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 most families this word will pass by without incident; it is more a vocabulary curiosity than a parenting concern.

For ESL learners

open house means: A house habitually kept open to callers.. Register: neutral, standard English. 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. A formal-English equivalent (a synonym or descriptive phrase) is usually safer in writing. When in doubt, paraphrase rather than reuse the slang form.
