When referring to time the suffix -ish means within plus or minus 15 minutes.
• You wake up at nine-ish every weekend.
• A: What time is the party?
B: At 8-ish.
• Shall I pick you up at sevenish?
When describing the colors of things we can add the suffix -ish, to say it is the hue of the color. For example, when I say “brownish”, it means that it’s kind of brown, not exactly brown, though.
• She has brownish-green eyes
• Michelle has reddish-brown hair.
