What does druidism mean?
Druidism is a noun referring to the religion, doctrines, and ritual practices traditionally associated with the druids — the learned priestly class of the ancient Celtic peoples of Britain, Ireland, and Gaul. In its primary sense it denotes an ancient faith about which remarkably little is known, since the druids left no writings of their own and most surviving accounts come from Roman authors such as Julius Caesar. The word is also applied to modern Druidism, a revivalist spiritual movement that emerged mainly during the eighteenth-century Romantic period and continues today, typically emphasising reverence for nature, seasonal festivals, and poetic inspiration. Used academically, 'druidism' carries a scholarly, historical register; used by practitioners, it describes a living tradition. It derives from 'druid' plus the suffix '-ism' and appears frequently in discussions of Celtic history, archaeology, mythology, and contemporary nature spirituality, making it useful in both historical and religious contexts.
The religious system, beliefs, and practices of the ancient Celtic druids.
"Roman writers left fragmentary and possibly biased descriptions of druidism."
Because the druids recorded nothing themselves, reconstructions rely on sparse external sources and should be treated cautiously.
A modern spiritual or religious movement that revives or reinvents the traditions attributed to the ancient druids; Neo-Druidism.
"Modern druidism gained momentum during the eighteenth-century Romantic fascination with all things Celtic."
We know almost nothing about what the ancient druids actually believed — they wrote nothing down — so most of what people call 'ancient druidism' was actually invented by eighteenth-century Romantics.

Etymology of druidism
Druidism is formed from 'druid' combined with the suffix '-ism', denoting a system of belief or practice. 'Druid' itself comes from Latin 'druides' (also 'druidae'), which the Romans borrowed from a Gaulish/Celtic term, often analysed as related to a root meaning 'oak-knower' (from Proto-Celtic *derwos, 'oak', plus a suffix meaning 'to know'), though the exact derivation is debated. English adopted 'druid' via French and Latin around the sixteenth century, with 'druidism' appearing later, by at least the seventeenth century, as scholars began writing about ancient Celtic religion.

How druidism is actually used
The term is used both historically/academically (for the religion of the ancient Celtic druids) and for the modern revivalist movement. Because very little is actually known about ancient druidic belief — druids left no written records — scholarly caution is warranted when describing it. 'Druidism' is somewhat more formal and older-fashioned than 'druidry', which many modern practitioners prefer as a self-designation.
Easily confused with druidism
Both refer broadly to Druid-related religion, but 'druidism' is the older, more scholarly/anthropological term for the beliefs of the ancient Celts, while 'druidry' is now more commonly used for the modern revival movement.
