Trink/trinkst; Is this a matter of feminine/masculine/neuter?
@phea It's a matter of person. Ich (I) is first person; Du (singular you) is second person; Sie, Er, Es (She, He, It) is third person. So trinke is first, trinkst is second and trinkt is third.
Maybe this will help remembering: if you read books in archaic English, such as old Bible translations, you may have noticed that there are sentences such as "thou drinkest". In today's English it's "you drink", but notice how similar "thou drinkest" is to "du trinkst".
Yes, it changes based on person: ich trinke, du trinkst, er,sie,es trinkt, Sie trinken, wir trinken, ihr trinkt, sie trinken. Another difference is verb stems ending in d, t, or a consonant cluster and verb stems ending in s, z, or ß are conjugated differently. http://gerxmanxney.tumblr.com/page/2
