📌 COULD - General Past Ability
Use 'could' to talk about abilities you had in the past in general (not a specific situation).
• I could run very fast when I was young.
• She could speak three languages as a child.
• He could play the piano at age five.
• We could see the stars clearly from our old house.
💡 Key idea: 'Could' = ability over a period of time (general)
📌 WAS/WERE ABLE TO - Specific Past Achievement
Use 'was/were able to' for a specific success in one particular situation.
• I was able to finish the marathon despite the rain.
• She was able to pass the exam even though it was difficult.
• They were able to escape the burning building.
• He was able to solve the problem after hours of work.
💡 Key idea: 'Was/Were able to' = a specific achievement (one event)
📌 Negative Forms (No difference)
In negative sentences, both 'couldn't' and 'wasn't/weren't able to' are used.
• I couldn't / wasn't able to finish the race.
• She couldn't / wasn't able to come to the party.
• They couldn't / weren't able to find the house.
