• SynonymよっぽどCasualA colloquial, emphatic form of 「余程」, as in 「よっぽど好きなんだね」; it carries an emotional, exclamatory tone.
• Synonym非常にひじょうにNeutralMeans very, as in 「非常に重要」; neutral in itself but leans toward formal, measured statements.

• Synonym極めてきわめてWrittenWritten and formal for exceedingly, as in 「極めて重要」.

• Antonym全然ぜんぜんCasualColloquial; with a following negative it means not at all, as in 「全然分からない」, the opposite of 「余程」 in this use; it can also add affirmative emphasis.

Use 「余程」 when the degree goes far beyond the norm, as in 「余程疲れたのだろう」. For emphatic colloquial speech pick 「よっぽど」, and for an ordinary very pick 「とても」. 「少しも」 and 「全然」 with a negative mean not at all — the opposite end of the scale.
