This lesson is covered in more detail in Week 8 of Introduction to Sindarin
The basic interrogative words, or question words (Who, What, Why etc.) are very useful in forming sentences. The verb endings and prepositions that you are introduced to here will be covered in detail in later lessons.
Man? = What? Who?
Man te? What is it? Who is it? Man sa? What is that? Who is that? Man i lû? What (is) the time? Man sad? What place? (alternative for 'Where?') Man agoreg? What did you do? Man na i fen? Who is at the door?
Alternative To avoid ambiguity when asking 'Who is it?' you could also ask Man pen? What person? (Who?)
