Why a cup that breaks 'easily' uses the word for easy

Where the picture shows up in 쉽다

1. 1

   work with nothing snagging

   이 일은 생각보다 쉬워요.

   i i-reun saeng-gak-bo-da swi-wo-yo

   This job is easier than I expected.

   A hand reaches into the pile of work on the desk, meets nothing that catches, and runs straight through to the end

2. 2

   words entering the ear unblocked

   선생님이 쉽게 설명해 주셨어요.

   seon-saeng-ni-mi swip-ge seol-myeong-hae ju-syeo-sseo-yo

   The teacher explained it in a simple way.

   A clumped-up lump of words is pulled apart into small pieces, and it flows from the ear into the head with nothing in the way

3. 3

   the slightest touch is enough

   이 컵은 쉽게 깨져요.

   i keo-beun swip-ge kkae-jyeo-yo

   This cup breaks really easily.

   A fingertip barely brushes the cup and it shatters on the spot without holding out for a second

   Here 쉽다 reads as 'tends to happen'. The picture is that nothing holds it back.

4. 4

   only the mouth has a clear path

   말은 쉽지만 하기는 어려워요.

   ma-reun swip-ji-man ha-gi-neun eo-ryeo-wo-yo

   Saying it is easy, doing it is hard.

   Words slide out of the mouth like a playground slide while the hands do not budge an inch

5. 5

   쉽지 않다 as soft weight

   혼자 아이를 키우는 건 쉽지 않아요.

   hon-ja a-i-reul ki-u-neun geon swip-ji a-na-yo

   Raising a child alone is not easy.

   The road ahead is strewn with stones, so each foot has to be lifted and placed one at a time

   쉽지 않다 is the softened way of saying 어렵다.
