💡 Grammar Points
Preterite Tense Focus
This form uses the simple past tense, which focuses on an action that started and finished at a specific point in the past (like meeting someone).
The 'c' to 'zc' Change
The base verb 'conocer' is slightly irregular because the 'yo' form of the present tense changes from 'c' to 'zc' ('conozco'). However, in this past tense form ('conocieron'), the stem is regular.
⭐ Usage Tips
Using 'Se' for Meeting
When talking about two people meeting each other, you usually need the word 'se' before 'conocieron' (Ellos se conocieron) to show the action was mutual.

💡 Grammar Points
Preterite vs. Imperfect
In the past tense, conocieron (preterite) means 'they found out' or 'they met' (a sudden event). Conocían (imperfect) means 'they knew' (an ongoing state of knowledge).
❌ Common Pitfalls
Mixing Past Tenses
Mistake: "Usando 'conocían la verdad' para decir que la descubrieron ayer."
Correction: Say 'conocieron la verdad.' Use the simple past ('conocieron') for the specific moment of discovery, not the descriptive past ('conocían').
