Admirable or hawk-like
Shaylin is a modern American invention likely combining the Irish name Shea, meaning 'admirable' or 'stately', with the popular 'lyn' suffix. Alternatively, it is sometimes associated with the Gaelic word 'seabhac', meaning 'hawk'. It represents the 21st-century trend of creating melodic, multi-syllabic feminine names.
