Does it make sense to let a colleague know about his repeated misspelling? I have been working on a project with a collaborator for several years. I have never met my collaborator in person but we've been a part of weekly calls and sent hundreds of emails together so I feel like at this point I know this person fairly well.
In what seems like hundreds (at least 10's) I have noticed my collaborator always misspells &quot;a lot&quot; as &quot;alot&quot;. This person is my senior (he's a graduate student, I'm a pre-doc) and I am wondering if I should let him know in a polite way that he is making a common misspelling. It does not particularly bug me or anything, and I am not a particularly fantastic speller myself, but I just want to help him out in case he doesn't know already. Does it make sense to bring this up with him as a colleague or is this not my place?
Let it go, while the typo is limited to emails. Emails are frequently written hastily and certain typos can be common or made on purpose to type less, or even for fun (I do sometimes this in my language, to mimic certain dialectal expressions).
If, instead, the typo appears in, for instance, a paper or other public document you're jointly writing, then correct it as you would correct any other typo in the paper.
