I'll give ya a hint.
The url in my new blog is an adjective.
Meaning:
1. disadvantage or damage; harm; loss
2. a cause of disadvantage or damage.
E.g: smoking is ___________ to health.
There's a '-' between the letter 'e' and 't',
and another '-' between 'i' and 'm'
Enjoy guessing! 8D
P.S: Another hint, it's in the Dunman Vocabulary book 2009 Lower Secondary.
If you're someone who's not in Dunman, that's your luck. :B
