and gender. Finite verbs agreed with their subject in person and number. Nouns came in numerous declensions (with deep parallels in Latin‚ Ancient Greek and Sanskrit). Verbs came in nine main conjugations (sevenstrong and two weak)‚ each with numerous subtypes‚ as well as a few additional smaller conjugations and a handful of irregular verbs. The main difference from other ancient Indo-European languages‚ such as Latin‚ is that verbs can be conjugated in only two tenses (vs. the six "tenses" – really

An examination of the porphyrin structure reveals that individual pyrrole units comprise the overall structure. As an aromatic compound‚ pyrrole can participate in electrophilic
