分别 vs 分别地 what is the difference?
Some words do not require 地 to be an adverb but we can add 地 to them to emphasizes 'the manner' of the subject
Examples:
一致反對 = unanimously oppose (the objection is unanimous)
一致地反對 = unanimously oppose (oppose in a unanimous manner)
猛烈攻擊 = fiercely attack (the attack is fierce)
猛烈地攻擊 = fiercely attack (attack in a fierce manner)
強力支持 = strongly support (the support is strong)
強力地支持 = strongly support (support in a strong manner)
In some cases, adding 地 can remove ambiguity. For examples: &quot;猛烈攻擊&quot; could mean [fierce(adj) attack (n)] or [fiercely (adv) attack (v)] while &quot;猛烈地攻擊&quot; can only mean [fiercely (adv) attack (v)]; &quot;強力支持&quot; could mean [strong (adj) support (n)] or [strongly (adv) support (v)] while &quot;強力地支持&quot; can only mean [strongly (adv) support (v)]
Another way to remove ambiguity is using 的 to indicate adjective and noun, e.g. 猛烈的攻擊, 強力的支持
