Other recorded senses(measured from records)
Illarion is also recorded in one other lexicon, as a different name or as an ordinary word. These are senses of the spelling, not of the name above.
Russian: from Greek Hilarion , a derivative of Hilarios (see HILARY ). St Hilarion ( c. 291– c. 371) was a famous hermit born at Gaza in Palestine; he desired to live a solitary, contemplative life, but was continually forced to move on by the crowds that flocked to follow him.
as a word
Ordered by how much of this spelling's record each language holds, so a sense from a language the name is barely used in sits last rather than first.

A formal English salutation is built on the surname, so it needs a full name — on its own, a first name only supports the informal form.

About this data
measured from records inferred from the name graph machine-generated
These figures come from the data snapshot of and will change as it is rebuilt.
Statistics are aggregated from the Mondonomo name corpus; related names and etymology are inferred from the name graph; pronunciation and any machine-marked transliterations are model-generated. Read how the numbers are made, including their known failure modes, and where the data comes from.
Reference works we consult — surname dictionaries, official name registers, Wikidata and Wiktionary — are named directly, beside the claims they support. The per-country source counts also include datasets of person records: we publish how many there are and their authority tier, but not their names.
