to need
'brauchen' and 'erfordern' can both express that something is necessary. 'brauchen' is the normal everyday word and works with people and things: you need help, time, or a tool. 'erfordern' sounds more formal and is often used when a task, situation, or goal requires certain skills, effort, or conditions. Learners may confuse the words because both have to do with necessity. In practice: when a person needs something, 'brauchen' sounds more natural. When a task requires something, 'erfordern' is often a better fit.
