I have long heard people say (what I thought was) “What is your read?” when asking others for their opinion of something. As if it were short for “What is your read of the situation?”
However, I ran across it spelled “rede” in Tolkien. Turns out “rede” is archaic English for “advice” or “counsel” and its usage can be traced as far back as Chaucer‘s Troilus and Criseyde.
So, forsooth, what is your rede?
