The present perfect progressive tense has two uses. It is used for:
A continuous activity that began in the past and continues into the present.
A continuous activity that began in past, but has now finished (usually very recently).
The present perfect continuous tense is formed:
[subject] + "has been" or "have been" + [present participle]
I have been working since yesterday evening.
She has been crying for two minutes.

If the verb ends in “ie," change the "ie" to "y" and add "ing":
tie > tying

If the verb ends in a consonant, double the consonant and add "ing":
