📚 Etymology

The Spanish verb 'ser' is highly irregular because it merged two different Latin verbs: *esse* (to be) and *sedēre* (to sit/remain). The conditional tense, however, is formed regularly from the infinitive (*ser* + -ían endings), a pattern established in early Romance languages.

First recorded: Old Spanish (Ser was established by the 10th century; the conditional form 'serían' follows the regular evolution of Romance conditional endings.)
