Adverb (Basic ㊦ 538)
An adverb indicating that the actual situation expectedly/anticipatively conforms to a standard based on past experience, comparison with other people, or common sense.
Equivalent: Still; also; after all; as expected; you know
1. やはり is a speaker-oriented adverb because its use is based on the speaker's subjective and presuppositional standards. Its overuse in conversation makes a discourse overly subjective, but its proper use in conversation makes a discourse sound like real Japanese.
2. やはり can be positioned sentence-initially or sentence-medially, just like other adverbs. Thus, in Key Sentence やはり can be positioned in two ways.
The sentence-initial やはり is more emphatic than the sentence-medial やはり. The sentence-final やはり as in (1c) sounds like an after-thought, and its usage is slightly marginal.
3. やっぱり is a more emphatic and emotive version of やはり, owing to its glottal stop 'っぱ'.

In [2] 結局 sounds more formal than やはり, because the former is a Sino-Japanese word, while the latter is a Japanese word. Yet both can be used in conversational Japanese.
III. The adverb まさか 'by no means, on no account, surely not' is used when a given situation is far from the speaker's expectation. In that sense, it is an antonym of やはり. まさか is used with a negative predicate or is used all by itself, meaning 'Unbelievable!, You don't say!'.
