Existing or present; in being.
From Latin 'ensiens' (present participle of 'esse,' to be), borrowed into English as a philosophical term. The word is primarily used in philosophical and metaphysical contexts to describe things that actually exist or have being.
This is a rare philosophical word that bridges Latin and English—it's barely used in modern English except in academic philosophy, but it represents an interesting moment when scholars needed vocabulary to discuss existence itself, so they borrowed directly from Latin verb forms.
