This is the 210th most frequent Indonesian word.
kurang
"Kurang" means "less" or "lacking."
'Kurang' here is used to mean 'slightly' or 'not completely.' It softens the degree of unwellness expressed.
Saya merasa kurang sehat hari ini.
I feel slightly unwell today.
'Kurang' in this context means 'lacks' or 'is insufficient in,' indicating a shortfall of a specific element (salt in this case).
Makanan ini kurang lagi sedikit garam.
This food needs a little more salt.
Here, 'kurang' contributes to the phrase 'kurang lebih,' which means 'more or less,' indicating an approximate time.
