The adjective 'hilfreich' (helpful) is made up of the noun 'die Hilfe' (help) and the suffix '-reich' (rich in). It literally means 'rich in help.'

'Hilfreich' (helpful) is often used with the prepositions 'für' (+ accusative) or 'bei' (+ dative). 'Hilfreich für' describes who or what something is useful for, while 'hilfreich bei' names the situation or task.

practical / virtually
'praktisch' and 'hilfreich' both describe something positive that has a use. 'praktisch' tends to mean that something works well in everyday life or is easy to use. 'hilfreich' more strongly means that something provides support with a problem or improves a situation. The words can be confused because a practical object is often helpful too. For things, solutions, or tools, 'praktisch' sounds very natural. For tips, explanations, or support, 'hilfreich' is often more precise.
