A spoken conjunction opening a sentence

colloquial-openeron by default (info)Japanese

A Japanese sentence opening with a spoken conjunction (なので, でも)

Example

What chaff prints

How to fix

Use the written conjunction (なので → そのため, でも → しかし).

Why it matters

In Japanese, なので, でも and だけど at the head of a sentence are spoken conjunctions. In a report or a notice they make that sentence sound casual. Written Japanese has words that do the same job (そのため, しかし). なので inside a sentence is ordinary and not checked.

What it does not flag

なので and でも inside a sentence, and written conjunctions (そのため, しかし), are not reported, nor is a "sentence" with only an auxiliary after the word (だからである。, the end of the previous sentence cut by a line break). Off for blogs, literature and speech.
