When should you use learned and when for past tense?

You're right to be confused! "Learned" and "learned" are both valid forms, but they have different meanings and uses.

Here's a breakdown:

"Learned" as the past participle of "learn":

* Meaning: To have acquired knowledge or a skill through study or experience.

* Use: Used in perfect tenses (present perfect, past perfect) and passive voice.

* Examples:

* I have learned how to play the piano. (Present perfect)

* She had learned the lesson by heart. (Past perfect)

* The students were learned by their teacher. (Passive voice)

"Learned" as an adjective:

* Meaning: Having or showing great knowledge or learning.

* Use: Describes a person or their knowledge.

* Examples:

* He is a learned scholar.

* The learned professor gave a lecture.

Here's a quick way to remember:

* "Learned" with an "e" at the end is an adjective.

* "Learned" without an "e" is the past participle of the verb "learn."

It's important to consider the context when choosing the right form.
