Generally misspellings like this kind of proves the point...
The comment means nothing, neither mine nor the one I commented on so I won't even bother looking up the spelling.
It's more important to understand why the comment is there.
The GP asked what boat, parent effectively said "a boat" which doesn't answer the question. My comment was one of the least likely options, but hey I could have said sailboat...
Not an excuse either but realistically I on a daily basis speak two languages and often interact with people who can barely speak one of those two so I have some basic understanding of a third... Sometimes I can't remember which one spelling rules come from. Not an excuse, it's easy enough to look it up but just context.
