So i've been studying some new wordplay lately, and I can't seem to really fully grasp these terms.. "There are a plethora of children at the mall." "There are myriads of children gathering at our local mall." Am I using Plethora/Myriad correctly?? "I don't have any time to listen to you spew your convoluted nonsense." I'm trying to substitute "stupid nonsense" for "convoluted nonsense." I'm guessing im using it slightly out of context? What word would you rather use in this situation? Next word is... Adverse. "Smoking weed can cause adverse effects to your body." Why do people put the word adverse next to effects all the time? Also what does it mean to patronize somebody? There are so many complex words floating around that I can't seem to fully understand all of them!! Thank you for your help.!
