Present Perfect

When talking about traditions, a very useful grammar structure is the present perfect with the prepositions for and since, and the question words how long, because it is used to talk about situations or activities that started at a specific time in the past and continue in the present.

Form	Structure	Example	Use
Affirmative	subject + have/has + past participle of main verb + complement or object	The danza del venado has been practiced in Sonora since the pre-Hispanic era.	Describe situations or activities that started in the past and continue in the present or activities that happened in the past with an important consequence in the present.
Negative	subject + haven't/hasn't + past participle of main verb + complement or object	Foreign folk dances haven't been common in Mexico.	(misma)
Interrogative	have/has + subject + past participle of main verb + complement or object + ?	Have you met someone who practices Mexican folk dances?	(misma)

When we want to know about the origin in time of an activity or situation that continues in the present, we normally use the question words how long:

How long have piñatas existed in Mexico?

To answer those questions, we have two main options:

We use present perfect with since to emphasize when the situation or activity started:

Piñatas have existed in Mexico since the 16th century.

Or we use for to describe the length of time an activity or situation has existed:

Piñatas have existed in Mexico for about 500 years.
