Here are some new words that I've learned while reading an ARC of The Swimming Pool by Holly LeCraw:
Muntin: a bar for holding the edges of window panes within a sash.
Here is how muntin was used on page 47:
He had not pulled down the shade of the window next to the bed, and moonlight was pouring through, so bright that the shadow of the crossed muntins fell on his chest.
Cuckold: the husband of an unfaithful wife.
Here is how cuckold was used on page 75:
He tried to look Marcella's former husband and cuckold in the face without flinching.
Tacit: understood without being openly expressed; implied.
Here is how tacit was used on page 142:
She suspected Jed had made a tacit pact with himself not to leave a trace.
So how about you? Have you learned any new words in your reading adventures lately?
