В чем разница между able----> respectable и ful------> respectful ?Пожалуйста, приведите примеры.

"~able" on the end of a verb creates an adjective that means you can do the action the verb describes. It's hard to explain but easy once you see some examples:

"to respect" -> respectable
"He is a respectable man." (He is a man who you can respect)

"to achieve" -> achievable
"That task is not achievable" (That task cannot be achieved)

"to drink" -> drinkable
"Is this old wine still drinkable?" (Can I drink this wine?)


"~ful" just means "full of", and is added to nouns to create an adjective. The opposite is "~less".

care -> careful (opposite is careless)

joy -> joyful (joyless)

thought -> thoughtful (thoughtless)

Unfortunately, it doesn't work for all words! Respect -> respectful, but respectless isn't a word!

Good luck!
