💡 Grammar Points
Yo vs. Él/Ella/Usted
In the imperfect tense, 'suponía' is the verb form used for both 'I' (yo) and 'He/She/You formal' (él/ella/usted). Context or the subject pronoun usually tells you who is doing the action.
The Imperfect Tense's Role
This tense ('suponía') describes a state of mind or a belief that was ongoing or habitual in the past, like 'I used to assume' or 'I was assuming,' without focusing on when the assumption ended.
❌ Common Pitfalls
Confusing Imperfect and Preterite
Mistake: "Using 'supuse' (I assumed—a single, completed action) when you mean 'suponía' (I used to assume—an ongoing belief)."
Correction: 'Supuse que estaba en casa' means 'I suddenly assumed he was home.' 'Suponía que estaba en casa' means 'I had been assuming he was home.'
⭐ Usage Tips
Guessing in the Past
Use 'suponía' when you are describing what you thought was true, but later found out was false. It sets the scene for a past error.

Frequently Asked Questions
How do I know if 'suponía' means 'I assumed' or 'He/She assumed'?
You usually figure this out from the context of the conversation or by looking at the subject pronoun (Yo, Él, Ella, Usted). If no subject is present, the surrounding verbs or nouns will usually make it clear who is being discussed.
Is 'suponer' a difficult verb to conjugate?
'Suponer' is considered irregular because it follows the pattern of 'poner' (to put), which has changes in the preterite ('supuse') and future/conditional ('supondré'). However, the imperfect tense ('suponía') is very regular, making this specific form easy to remember.
