why does agradecer change into agradecido in the sentence "Estoy muy agradecido."

Question

why does agradecer change into agradecido in the sentence "Estoy muy agradecido."

Answer 1

This is because it is the past participle of the verb, and is being used as an adjective describing how you feel.

Think about the English word "to delight".

I was delighed to see him. Here it is a part of the verb construction.

I am delighted (that I saw him). In this sentence it is a predicate adjective describing the speaker telling how the speaker felt.

Every verb has a past participle.

love - loved

run - ran

sleep - slept

When you use them as adjectives, they are neither past nor present in and of themselves.

The verb in your sentence will give you the time.

I am delighted (present).

I was delighted (past).

Hope that helps.

But I am trying to say "I am grateful.", and that is the translation I was given. So you are saying this is the past tense? I was trying to use it in the present tense that "I am". - gwenyd2, JUN 23, 2010

That's right, as in Delores example above - I am delighted - present tense - Kiwi-Girl, JUN 23, 2010

Estoy agradecdo. (masc.) Estoy agradecida. (fem) - Delores--Lindsey, JUN 23, 2010

Answer 2

Because its being used as an adjective in that sentence.
