Don't confuse with

加か減げんN3
加減 alone just means 'degree' or 'adjustment' (as in 湯加減), while いい加減 is a separate word meaning careless, vague, or 'enough already'.

Etymology

A compound of いい, 'good,' and 加減, 'degree, adjustment, moderation.' The older literal idea of a suitable degree helps explain the 'enough' and 'considerably' uses, while many modern uses have shifted to negative meanings such as careless, vague, or halfhearted.
