look out

watch carefully so you notice someone or something

B1

What does "look out for sb/sth" mean?

To 'look out for' something or someone means to stay alert and pay attention in case it appears or happens. You are not actively searching — instead, you are keeping your eyes open while you go about your day. For example, a friend might tell you to look out for ice on the road, meaning you should be ready and watching in case it is there. The phrase also has a second meaning: to protect someone and watch over their interests, like an older sibling who always makes sure their younger brother or sister is safe. Both meanings involve a sense of care and readiness.

Frequently Asked Questions

Does 'look out for' always mean something dangerous?

No — it can refer to things that are positive or neutral too. For example, you can look out for bargains, opportunities, or useful information. The idea is simply that you stay alert and ready to notice something when it appears.

What is the difference between 'look out for someone' and 'look after someone'?

These are close but not the same. 'Look after someone' means you are actively taking care of their daily needs — feeding them, keeping them safe, and so on. 'Look out for someone' means you are watching over their interests or protecting them, but not necessarily doing hands-on care. You might look out for a friend at work by warning them about a problem, rather than doing things for them directly.

Can I say 'look out for yourself'? Does it sound selfish?

It depends on the context. 'Look out for yourself' can mean protect your own wellbeing, which is perfectly positive — for example, 'Make sure you look out for yourself while you're travelling alone.' However, in some situations it can suggest being self-interested at the expense of others, so the meaning is usually clear from the situation.

Can 'look out for' be used in written English, or is it only for speaking?

It is common in both spoken and written English. You will find it in travel guides, health advice articles, safety notices, and everyday emails, as well as in normal conversation. There is no restriction on where you can use it.

Is 'look out' (without 'for') the same thing?

'Look out!' on its own is usually a sudden warning about immediate danger — like shouting it when someone is about to trip. 'Look out for' requires an object and talks about ongoing alertness over time. They are related but work differently in a sentence.
