What is the name for words which, when the order of letters is reversed, spell other words? [duplicate]

For example:

• Lamina / Animal
• Dog / God
• Ogre / Ergo
• Desserts / Stressed
• Tuba / Abut

These are all anagrams, but they are a special type of anagram, where the order of letters is exactly reversed. They aren't palindromes, as they spell a different word when read backwards. I feel like there should be some sort of latin-sounding name for them, but the best I can come up with is the rather imprecise-sounding "backwards words", "mirror anagrams" or "reverse spelling pairs"...

Solution 1:

I have seen a couple different terms used for this. The first is anadrome and the second, more facetiously, is semordnilap. They both mean essentially the same thing: a word (or phrase, as is the case with semordnilap) that spells another word or phrase backwards.
