dokkai 読解 どっかい
In translation from Japanese dokkai (読解, どっかい) stands for reading comprehension or to understand what one reads.
The first kanji in this term 読 is translated as to read and the second 解 may mean a whole array of words:
- divide; split; separate
- untie; loosen; relax; remove
- make clear; explain
- understand; comprehend
- opinion; explanation; solution
Those studying Japanese language increase their skills by reading numerous field-specific booklets to improve their reading comprehension. After all, Japanese Language Proficiency Test (JLPT) has a dedicated session just to dokkai.
There are plenty of such studying materials on the Internet shops, including Amazon and Scribd.com. LPT N3 Nihongo Somtome Reading Dokkai Asuku (NIHONGO SO-MATOME (KANJI) (3)) is a good example of such a material.
