straff vs fest
firm / fixed
'fest' and 'straff' can both describe something that is not loose. 'fest' is more general: a table, a knot, or a grip can be 'fest' if it holds firmly or is done with force. 'straff' is especially fitting when something is taut, smooth, or without wrinkles, for example a rope, fabric, or skin. Learners may confuse the words because both are opposites of 'locker' (loose). As a simple guide: 'fest' is more about hold or strength, while 'straff' is more about tension and smoothness.
straff
Nach dem Waschen hing das Tuch straff auf der Leine.
After washing, the cloth hung taut on the line.
fest
