けどMais, Cependant

Both が (or だが/ですが after a noun or な-adjective) and けど・だけど express contrast or transition, similar to 'but' in English (e.g., '見た目は美味しそうだけど、味がない' = 'It looks tasty, but has no flavor'). The difference is that が is more formal or written-style, while けど is more colloquial. Both can also be used at the end of a sentence to suggest an implied contrast, even if not explicitly stated.

Both けど・だけど (and the polite ですけど), as well as だが・ですが, express contrast, similar to 'but,' or sometimes just indicate a transition (like 'and'). The key difference is that だが is more formal and used in written contexts, while けど is more casual. Both can be used at the end of a sentence to imply something is left unsaid.

けど and けれども are essentially the same expression, with けど being a shortened form of けれども. Both express contrast, like 'but' in English, or soften a statement. The difference is in their formality: けど is casual and colloquial, while けれども is more formal and is most often used in writing or formal speech.

Les deux expressions けど et だけど introduisent un contraste, similaire à « mais » en français, et sont fréquentes à l'oral, comme dans 難しいけど面白い (« C'est difficile, mais intéressant. »). En ajoutant ～ん à cette structure, on apporte une nuance explicative, souvent utilisée pour exprimer une demande indirecte ou une hésitation, par exemple 難しいんですけど, qui pourrait être compris comme « C'est difficile, mais... (souhaitez-vous que je le fasse quand même ?). »

Both ところが and けど・だけど express contrast or contradiction. The key difference is that ところが is used at the beginning of a sentence to emphasize a contrast between the expected result and reality, and is more formal. In contrast, けど・だけど are used after a phrase or at the end of a sentence to express simple contrast or contradiction.
