[subject] + 也 + [verb phrase]
[object] + [subject] + 也 + [verb]
[clause],[subject] + 也 + [verb phrase]
怎么 / 再 + [verb],也 + 不 / 没 + [verb]
也 has one position – after the subject, before the verb – but what it adds can be any part of the sentence. 我也喜欢喝茶 can mean "I like tea too, like you" or "I like tea too, as well as coffee". Speech settles it by stress and context.
To make clear that the object is what is added, move it to the front as the topic. 也 stays where it was.
English puts "too" next to the word it adds. 也 can't follow the object.
When the subjects differ, 也 can add one whole event to another. The "also" covers the clause, not a single word.
After 怎么, 再, or a question word, 也 says the outcome holds whatever happens. Here it adds nothing; it marks the result as unchanged. 即使…也 works the same way.
也好, 也行 and 也可以 accept a second-best: "that's fine too", "might as well".
