The adjective 'verführerisch' (seductive/tempting) is derived from the verb 'verführen' (to seduce/tempt). 'Verführen' means to lead someone into doing something that they can only resist with difficulty. Something that is 'verführerisch' therefore has the quality of being able to 'verführen' someone.
Lass dich nicht von den süßen Snacks verführen!
Don't let yourself be tempted by the sweet snacks!
If 'verführerisch' refers to people, their appearance, or their behavior, it usually means romantic or erotic attraction. If it refers to offers, food, or ideas, it means 'very tempting'.
Sie warf ihm einen verführerischen Blick zu.
She gave him a seductive look.
In the meaning 'verlockend' (tempting), the word is often used for sensory impressions and abstract things. Common combinations are 'ein verführerisches Angebot' (a tempting offer), 'ein verführerischer Duft' (a tempting scent), or 'ein verführerischer Gedanke' (a tempting thought).
Die Idee, einfach alles stehen und liegen zu lassen und zu verreisen, war verführerisch.
The idea of simply dropping everything and going away was tempting.
sexy
'sexy' and 'verführerisch' can both describe someone or something as very attractive. 'sexy' says more directly that something is sexually attractive or especially desirable. 'verführerisch' emphasizes the effect on a person more strongly: you feel like having something or can hardly resist. This can be meant erotically or romantically, but it can also fit food, offers, or beautiful things. 'sexy' often sounds more modern and casual, while 'verführerisch' sounds a bit more vivid and describes the temptation more.
