掐

qiā - pinch, pick (flowers)

I heard this word on a Popup Chinese podcast and realised it was the first time I'd heard a Chinese word with the sound 'qia'. MDBG confirms that there are very few 'qia' words and this is the only one with a first tone. Interestingly, 卡, which I had learnt has being pronounced kǎ, can also be pronounced qiǎ.
