"An owl is a bird."
Translation:Een uil is een vogel.
Een is a-an in english. En is and in engish
And personally with langauges that are closely related like dutch and english, you can expect some words like uil and owl (both meaning the same thing) sound very similar but are spelled differently. For this i suggest learning how to pronounce the dipthongs in dutch. Other than that treat the langauge like its rules and structure MUST be abided by even if its the opposite of english.
