trainierst

Trainierst is the second-person singular present tense of the German verb trainieren, meaning to train, practice, or exercise. It is used when addressing someone informally with du. For example: Du trainierst jeden Morgen.

Origin and form: The verb trainieren was borrowed into German in the 19th century, likely from English train or French entraîner, and then formed with the common German -ieren suffix. The base verb is trainieren; present tense forms include ich trainiere, du trainierst, er trainiert, wir trainieren, ihr trainiert, sie trainieren. The older, archaic form trainierest exists mainly in historical texts but is not used in modern speech.

Usage: Trainierst appears in contexts of physical exercise, sports preparation, or general skill development. It takes a direct object indicating what is trained: Du trainierst deine Muskeln; Du trainierst dein Gedächtnis. It can also be combined with time expressions: Du trainierst jeden Tag zwei Stunden. The form is common in everyday language, fitness contexts, and descriptions of practice routines.

See also: trainieren; das Training; der Trainer. Notes: The noun referring to a person who trains is usually der Trainer, not eine Form of trainieren. The term trainieren should not be confused with other related German verbs or nominalizations; its meaning remains centered on structured practice and repetitive exercise to improve ability.
