'Wand' is a very productive base word for compounds. Examples include 'Wandfarbe' (wall paint), 'Wandschrank' (built-in wall cabinet), 'Kletterwand' (climbing wall), or 'Brandwand' (firewall/fire wall).
Für das Kinderzimmer brauchen wir eine abwaschbare Wandfarbe.
For the children's room, we need washable wall paint.
You can easily recognize the meaning of 'Wand' from context: in sports, it refers to the defense; in climbing, to a rock face; and in a house, to the boundary of a room.
Die Abwehr stand heute wie eine Wand und ließ kein Tor zu.
The defense stood like a wall today and did not allow a single goal.
The idiom 'mit dem Rücken zur Wand stehen' means that you are in a very difficult, hopeless situation and have no options left.
Nach den hohen Verlusten stand die Firma mit dem Rücken zur Wand.
After the heavy losses, the company had its back to the wall.
Pay attention to the case after the preposition 'an' (on/at): 'an die Wand' (accusative) describes movement, while 'an der Wand' (dative) indicates a position.
Ich hänge das Bild an die Wand.
I am hanging the picture on the wall.
The idiom 'gegen eine Wand reden' is a fixed structure. It describes the frustrating feeling when another person is not listening to you at all.
Ich habe versucht, ihn zu warnen, aber es war, als würde ich gegen eine Wand reden.
I tried to warn him, but it was like talking to a wall.

'die Wand' and 'die Mauer' can both mean a solid vertical surface made of stone, concrete, or similar material. The most important difference is the typical place and purpose. A 'Wand' usually borders a room inside a house or divides an interior space. A 'Mauer' often stands outside, marks off a property, or protects and supports something. Learners may confuse the words because a 'Mauer' can look like a 'Wand', and both can be part of a building. As a guide: in a room, you almost always say 'Wand'; in a garden or at a boundary, 'Mauer' is more likely.

Im Wohnzimmer hängt ein großes Bild an der Wand.
There is a large picture hanging on the wall in the living room.
Luis hat hinter der Mauer im Garten einen kleinen Platz zum Sitzen gebaut.
Luis built a small place to sit behind the wall in the garden.
