Images down below is a question with two parts

naming a chemical compound. I'm currently learning how to name alkanes and alkyl halides. Im confused about the compound ethanal, or acetaldehyde. The second carbon has a double bond on its hydrogen, so I'm wondering why the infix is "an" instead of "en". Frpm the table of infixes, it says "an" is for single bonds. Can someone help me understand
