Describes the visual impression of a subject.
Use 'look' for the action of trying to see (voluntary). Use 'see' for the ability to perceive (involuntary). Example: 'I looked at the bird, but I didn't see it clearly.'
Always use 'look at' when specifying an object. Do not say 'I look the picture'; say 'I look at the picture.'
From Old English lōcian, of Germanic origin; related to Dutch loken and German locken.
Unlike 'see', 'look' implies a voluntary action of directing attention. Use 'look at' for specific objects and 'look for' when searching.
