“Here - let me take a look.”

Your coworker is trying to change the color of some text on a spreadsheet document on his computer, but can't figure out how to do it. You think you know how, so you offer to help:

Here - let me take a look.

Here -

People often say "here" before offering to help or take responsibility for something. A few more examples:

Here - let me do that

Here - I'll hold this while you tie it up.

take a look

The word "look" is very general. It can mean to look for a long time, a short time, carefully, absent-mindedly, or in many other ways. "Take a look" is more specific. It means to look at something for a short period, usually for a specific purpose.

You can ask someone to take a look at something that needs to be fixed, or for something that's important for them to see. Here's another example from a science classroom. The teacher tells the class to look at something in the text book:

Everybody take a look at the picture on page 46. This is a model of what a strand of DNA looks like.
