'Montagmorgen' (Monday morning) is a compound noun made from 'Montag' (Monday) and 'Morgen' (morning). This pattern works for all days of the week, for example 'Dienstagmorgen' (Tuesday morning) or 'Freitagmorgen' (Friday morning).

To indicate a point in time, 'Montagmorgen' (Monday morning) is used with the preposition 'an' (on), which is usually shortened to 'am'. The question for this is 'Wann?' (When?).

'der Montag' and 'der Montagmorgen' both refer to the first day of the working week. The difference is the time: 'der Montag' means the whole day, from morning to evening. 'der Montagmorgen' means only the morning or late morning of that day. Learners can confuse the words when they want to specify the exact time of an appointment or action. If only the day of the week matters, you say 'Montag'. If it is specifically about the early part of the day, 'Montagmorgen' is more precise.
