Note: Always trisyllabic, exact realisation of the vowel junction unknown. Length of final vowel impossible to establish, in all likelyhood parallel to simplex ubī̆. Invariably stressed on first syllable in iambic verse unless forming a word-group with erit.[1]
Wherever he is, make sure he hears this first thing.
Usage notes
The adverbs ubī(“where”), ubinam(“where in the world?”), ubicumque(“wherever”) and ubiubī are sometimes used with the genitive of terra(“land”) (plural: terrārum), locus(“place”) (singular: locī, plural: locōrum), gens(“nation”) (singular: gentium), to detonate the same meaning as "where on earth". "in what country" or "where in the world":
† Turned conjunction with original meaning somewhat dissimulated ° Rare ‡only used as a conjunction, not as an interrogative
