<span>A. cultural diffusion
It's where culture and language spreads across large distances.
Hope this helps :)</span>
<span>In Spanish, the words</span><span> tú and </span>usted <span> both mean “you". However, tú is much less formal than </span>usted<span>.
So, you </span>use<span> tú when you're talking to someone of the same age, the same rank, or the same educational level, but when talking to someone who's considered a high rank, maybe a grandparent, you would use usted.</span>
