Coltish is an adjective that means energetic, but awkward.

Our word of the day takes the word for a young male horse (colt) and combines it with the suffix I-S-H to mean something resembling a colt. The resemblance is related to the fiery spirit of young horses. A coltish person can be one who behaves wildly and recklessly.

It embarrasses me to recall all the crazy behavior I engaged in as an adolescent. I was so coltish and wild, I’m lucky I didn’t wind up in jail.
