Was (question word)
Used to ask 'what' in a neutral‑question; it triggers inversion of the verb.
ist (sein)
Third‑person singular present of 'to be'; in questions it follows the question word.
dein (possessive pronoun)
Shows ownership; it must agree with the gender, number and case of the noun (here neuter nominative, so 'dein').
Lieblingsfach (compound noun)
A compound of 'Liebling' (favorite) + 'Fach' (subject). The main noun is 'Fach' (neuter), so the article and adjective endings follow neuter rules.

✕Common Mistakes
Was ist deine Lieblingsfach?
Fach is neuter, so the correct possessive is 'dein', not the feminine 'deine'.
Was ist dein Lieblingsfaches?
Do not add an ending to the compound noun; 'Lieblingsfach' stays unchanged in the nominative.
Welcher ist dein Lieblingsfach?
Use 'Was' for a neutral question about identity; 'Welcher' would require a noun after it (e.g., 'Welcher Fach ist dein Lieblingsfach?').

Cultural Tip
In Germany the school system distinguishes between "Grundschule" (primary), "Gymnasium" (academic high school), "Realschule" and "Hauptschule". The word 'Fach' can refer to any subject taught at any level, but in university contexts it often means a specific module or course. When you ask a German about their Lieblingsfach, they may answer with a broad field (e.g., "Mathematik") or a more specific course (e.g., "Statistik"). Using the informal 'du' form is normal among peers, but switch to 'Sie' if you’re speaking with a teacher or a professional you don’t know well.
