Looking for to better understand aspects

I've been into astrology for a while, but I've recently gotten back to it after a couple years of not really paying too much attention. Now I really am trying to learn more about transits,aspects, etc. I read square, conjunct, trine, opposition, sextile, etc and get so lost. I've googled for answers but I think I also need examples of each aspect for it to really set in. If anyone can help me out, I'd really appreciate it!
