+## Escaping `\<` is required in `[..]`, but invalid in `[[..]]`
+
+### Problematic code:
+
+```sh
+[[ aardvark \< zebra ]]
+```
+
+### Correct code:
+
+```sh
+[[ aardvark < zebra ]]
+```
+
+### Rationale:
+
+Grammatically speaking, `[` is considered a normal command name, so `<` and `>` are interpreted as redirections. When using the lexicographical string operators `<` and `>` in `[ .. ]`, they must be escaped (e.g. `\<` or `"<"`).
+
+`[[` is considered its own grammatical construct, and therefore it does not require (nor does it allow) escaping `<` or `>`. 
+
