The particle しき greatly resembles だけ, but it is no longer used a lot and is very limited in usage.
しき is seen after これ, それ, and あれ to express that something is "only about...much". The particle しき derives from 式 meaning "style". しき is synonymous to the pattern たかが…くらい.
It's just this much.
Don't whine about such an insignificant problem.
Don't worry cause it's only just that much.
You mustn't be astonished at such a mere thing as that.
Orthography Note: You may write しき in 当て字 as 式.
This year, my primary goal is completely revamping the curriculum. Unfortunately, a vehicle emergency involving my one and only vehicle is jeopardizing my ability to focus on the site. I'm hoping to have the curriculum ready to be available in other mediums within the next three months, but my inability to commute to work would hault all work here.
Any help would be greatly appreciated.
