To complement the writeup already here:
死体「したい」 - Shitai
「死」 - Kanji representing death.
「体」 - Kanji representing the body.
---------------------
Shitai also has other meanings, depending on kanji (and in speech, by context), including:
姿態 - which means figure, form, or style,
肢体 - limbs, members, body, and
屍体 - a cadaver, and
支隊 - a task force
This highlights the core weakness behind the use of romaji, especially when learning Japanese.
