For everyday 'love', 「愛する」 is the standard choice; 「愛す」 means the same and conjugates as 「愛さない」「愛します」, but is much rarer. Use 「好く」 for lighter 'like', 「好む」 for preferences, 「慈しむ」 for a senior's tender care, 「慕う」 for admiration, 「恋い慕う」 for yearning, 「恋する」 for romance, and 「惚れ込む」 for deep captivation; 「好き好む」 is for doing something purely by choice. 「愛慕」「恋慕」「恋着」 belong to the written register, and 「愛しがる」「愛おしがる」 are written words seldom used. Antonyms: 「憎む」 for hate, 「嫌う」 for dislike.
