Today at a progress meeting I heard a colleague say:
あのじわじわじわじわ進んでまして
I discovered that 「じわじわ」 is similar to 「どんどん」 and 「だんだん」, is used to express that something is progressively advancing, but sloooowly.
I love these Japanese onomatopeias with repeated sounds, sounds so funny.
Indeed!
I’ve suggested a 擬態語/擬音語 deck and, in the Shiritori OP, I’m currently playing just with this kind of words. They’re a whole new world, quite difficult to master.
じわじわ行っても頑張ろう！
*onomatopoeias 
庭には二羽鶏がいる
Have a few beers then read ten times…
I love this phrase, lol.
I’m personally more biased towards
裏庭には二羽、庭には二羽、鶏がいる
エニワン would be!
