Translation:A man reads.
that was confusing... lezen? leest? :(
These are forms of the verb "lezen". In English there is read and reads, in Dutch there are more different conjugations. See here for more information.
To understand how "lezen" turns into "leest" (doubling of the vowel, z turns into s), take a look here.
How is "een" pronounced? I hear /un/.
the last word was really hard to understand
