Liam (English)

Where does "Liam" come from?

The English given name 'Liam' comes from Irish 'Liam'[1], which is a clipping of 'Uilliam'[3]. 'Uilliam' traces back through Middle Irish 'Uilliam' and Middle English 'William'[8] to Anglo-Norman 'Willame' and Old High German 'Willahelm'[2]. This ultimately derives from Proto-Germanic '*Wiljahelmaz'[2], a compound of '*wiljô' meaning 'will' and '*helmaz' meaning 'helmet'[6]. These root elements stretch back to the Proto-Indo-European roots '*welh₁-' meaning 'to choose, wish, want' and '*ḱel-' meaning 'to cover, conceal, save'[2].

Open questions

The Proto-Germanic noun '*helmaz' is probably derived from the Proto-Indo-European root '*ḱel-'. [2] [7]
