Admirable or hawk-like
Shayle is a modern English coinage, likely blending the Irish name Shea, meaning 'admirable' or 'stately', with the popular 'lee' or 'ayl' suffix. It may also be interpreted as a variant of the English surname Shail, which is thought to derive from a nickname for someone who walked in a crooked manner or related to the word for a hawk.
