"The woman is reading the recipe."
Translation:Die Frau liest das Rezept.
One way is that many words have suffixes which determine the gender. For example, nouns ending in ‘-ette’, ‘-ie’, ‘-ik’, ‘-in’, ‘-ine’, ‘-keit’, ‘-schaft’, ‘-tät’, ‘-tion’, ‘-tur’, or ‘-ung’, are almost always feminine; nouns ending in ‘-er’, ‘-ismus’, or ‘-ist’ are mostly masculine; and nouns ending in ‘-chen’, ‘-lein’, or ‘-o’ are almost always neuter.
Here is how I do it: For der (m) words imagine David Hasselhoff with the object. For die (f) imagine Heidi Klum with the object. For das (n) words imagine E.T. with the object. I got the idea from this guy http://www.bbc.co.uk/languages/german/comedy/, though he suggests Angela Merkel for the feminine.
Every German noun has one of three genders: masculine, feminine, or neuter. Depending on its role in the sentence, a noun can be in one of four cases: nominative, genitive, dative, or accusative. In the nominative case (used mostly for the subject), the definite articles are ‘der’ [masculine], ‘die’ [feminine]; and ‘das’ [neuter]. In the accusative case (used mostly for the direct object), the definite articles are ‘den’ [masculine], ‘die’ [feminine], and ‘das’ [neuter]. ‘Rezept’ is neuter, so it takes the neuter definite article ‘das’ in both the nominative and (as in this sentence) the accusative.
