-ISH. A very useful suffix
'I'll see you at three-ish !'
translation: We'll meet at approximately three.... but I might be a little late!
-ISH is something I use so often that it never occurred to me you need to learn about it, or that it was a real grammatical thing.
(It's also the name of a rather delicious brand of London dry gin).
So how do you use it? And when??
You can use -ish to approximate a number e.g. two-ish, to approximate a quality e.g. tallish (taller than me but not ridiculously tall).
Possibly the most useful use is for when we can't think of a better way to describe something, most typically used by men to describe colours of clothes 'greenish' rather than turquoise for example!
Usually, you use a hyphen (be creative, you can add it to most things if you're confident about it!) unless it's such a frequent collocation that it's been absorbed into common spelling e.g. 'the shortish woman at the bus stop'.
