grammarDetailPage.commonMistakes.why: 同じだ is a neutral statement that things are the same, whereas も同然だ means “practically” or “as good as” the same and often expresses an emphatic judgment.
Key points
Use this when an action, state, or result is practically equivalent to A, even if it is not literally identical. Verbs usually appear in the plain past form or negative form; the expression is emphatic and is often used in assertive or somewhat formal speech and writing. Unlike neutral 同じだ, it means “effectively the same,” and unlike 当然だ, it does not mean “natural” or “expected.”
