бути

• буть (butʹ)
• быть (bytʹ) – archaic

From Old East Slavic бꙑти (byti), from Proto-Slavic *byti. The u in the infinitive and past tense was probably influenced by the future tense. Compare (rare and possibly hypercorrect) Old Novgorodian буть (butĭ) for the infinitive and Belarusian быць (bycʹ) for the senses.
