Pleco is the most popular dictionary for learners of Chinese. I use Pleco for its clip reader tool, and to look up words I already know but forgot how to write. But as a dictionary it's just awful, and its paid version is not better.
Here are the results for "slam". Any English speaker would think of "slam a door" (摔门) but look at the garbage Pleco turns up:
满贯:To reach a perfect score in Mah-Jong
全胜:To achieve total victory
碰碰:(onom.) bang bang
乓:(onom.) bang
灌篮:Slam dunk
猛力:With all one's force
猛撞:To smash into
关门:To close (a door)
扣篮:slam dunk
如樽:slam dunk
大满贯:grand slam
急刹车:slam on the brakes
爆扣:slam dunk
李娜:A famous Chinese tennis player
抱摔:body slam
赶紧:slam on the brakes
飞身:slam dunk
FIVE words for "slam dunk" and not a single word for "slam a door"? Why does anyone take this app seriously as a dictionary?
