  • Ser is an irregular verb, making it trickier to learn.
  • Don’t worry about memorising all the conjugations perfectly. Through speaking and listening on a regular basis, you’ll become able to conjugate verbs correctly most of the time even if you don't remember the rules and exceptions off by heart.
  • If you want help with grammar, or you just want to become fluent in Spanish, you may want to take personalised 1-on-1 lessons.

Here's a reminder of what the Spanish personal pronouns mean:

  • yo = I
  • tú = you (informal)
  • él/ella = he/she
  • nosotros/nosotras = we
  • vosotros/vosotras = you (plural, informal, Spain only)
  • ellos/ellas = they
  • Usted = you (singular formal) & ustedes = you (plural formal). These are used much more in Latin America than in Spain - the latter being more informal.
