💡 Grammar Points

The Simple Past Tense

This form, 'supuse,' is the simple past ('preterite') for the 'yo' (I) form. You use it for actions that started and finished completely at a specific point in the past.

The Irregular 'Poner' Pattern

'Supuse' is irregular because it follows the pattern of the verb 'poner' (to put). Remember the 'pus-' stem for all simple past forms: 'supuse', 'puse', 'compuse', etc.

❌ Common Pitfalls

Using the Regular Ending

Mistake: "Yo suponí"

Correction: Yo supuse. The simple past of 'suponer' does not use the regular '-ía' or '-í' endings; it uses the special, irregular '-e' ending.

⭐ Usage Tips

Focus on Deduction

Use 'supuse' when you made a guess or a deduction based on evidence you had at the time, but you weren't certain. It implies less certainty than 'I knew'.
