Yeah, the Tips & Notes say "Swedish does not like when two vowels are next to each other, so you drop the "e" in the preceding syllable." I'm confused also.
Monosyllabic neuter words work like this: te -> teet, trä -> träet ('wood').
dricker is the verb 'drinks' or 'is drinking'
drycker is the plural of the noun en dryck which means 'a drink' as in 'a beverage'.
Iv'e seen alot of translation questions talking about men drinking tea xD
