Liam
Masculine · “will”
Liam is overwhelmingly a boys’ name — 358,536 boys against 549 girls since 1880. See Liam as a girl name
Liam began as an Irish clipping of Uilliam — the Irish form of William — and for generations it was the everyday name you used at home while the parish register said something longer. It has since gone out into the world on its own, charting in Ireland's neighbors and across the Atlantic, and it still sits easily in the mouth: two open syllables, LEE-am, over almost as soon as it starts.

Where it comes from
From Willahelm to Liam
The story of Liam
The parent name was Germanic: Willahelm, formed from wil ('will, desire') and helm ('helmet, protection'). It traveled into Old French as Guillaume and crossed to England with the Normans in the eleventh century, where William became one of the most heavily used men's names for the next eight hundred years. Irish speakers took it in as Uilliam, and Irish habit trimmed the front off it to give Liam. That short form stayed largely Irish for a long stretch, then spread through the English-speaking world as an independent name in its own right.
Meaning
will, desire + helmet, protection
From the Germanic elements wil and helm, usually read together as something like 'resolute protection'. Liam carries that meaning at one remove, as the shortened form of Uilliam/William.

The James test
Every popular name lives one long story — a climb, a peak, a slow settling back. Liam's later chapters haven't been written yet, so we borrowed them: James climbed just as high around 1940, and its whole arc is on record. Line the two peaks up, and James's path sketches the road Liam is walking now.

The trade-off
- Spelled the way it sounds, and familiar enough that most people will get it right the first time without a repeat.
- Sits behind William, a name with an unbroken record in English since the eleventh century, so a longer formal version is available if wanted.
- Two syllables and four letters — quick to say, quick to write, easy for a child to learn early.
- Charts in several countries at once, including Canada, France, Scotland and England & Wales, so it needs no translation abroad.
- It is one of the most-used boys' names in the country right now. A Liam is likely to meet other Liams at school and may end up going by Liam plus a last initial.
- Because it is already a short form, there is little room to shorten it further — you get one name rather than a set of options.
- Its wave is very recent, so nearly every Liam alive in the US is young. That reads fresh now, but it will date the name to this generation later on.
