I guess I just found a little typo here:
“In English (and many other languages), the imperative tense is used to give commands”. That should the “mood” not “tense”, I suppose.
No, tense is totally fine, it’s not a typo. w/r/t language in general, tense is afaik more common, it’s more specific. w/r/t to ‘imperative’ in particular dunno if it’s a US thing that “imperative mood” is more common but I was only ever taught tense in school (UK)
