Etymology: The root here is the Latin noun "ulcus", meaning a sore or open wound, which traces back to a Proto-Indo-European root for "wound" or "to burn" (the exact sense is debated). Latin turned it into the verb "ulcerare", "to make sore or to cause to ulcerate", and the past participle "ulcerātus" supplied English with its base form. The Latin verb carried the sense of a wound that spreads and does not heal, which is why medical writers reached for it when describing sores that eat into flesh. English borrowed the verb "ulcerate" directly from that Latin source, so it sits among the many technical medical terms that came straight from Latin rather than through French. The "-ing" ending simply turns the verb into a participle and gerund, letting writers describe a process still underway: a wound that is actively breaking down rather than one that has already formed.
