Brickbat is a noun that refers to an uncomplimentary remark.
Our word of the day is a portmanteau, meaning it combines more than one word. In this case, we get the combination of ‘brick’ and ‘bat’ to get a word that, when used literally, refers to a something used as a weapon. But when used figuratively, it may refer to something like an unkind remark. For example: My question about Chad’s tiny apartment wasn’t intended as a brickbat. I just wanted to know if it offered enough space to host the upcoming new year’s eve party.
