Spanish verbs fall into different groups, and each group is conjugated a little differently. If you’re going to master Spanish verbs like nadar, you need to be able to identify which group a verb belongs to: regular (follows regular conjugation rules for -ar, -er, and -ir verbs), stem-changing (morphs depending on how you use it in a sentence), spelling-changing (has consonant-spelling changes in some forms to follow pronunciation rules), or reflexive (reflects the action back on the subject of the sentence).
