green group · The short answer
FASTEN
Each puzzle word passes the same exact test. The four mappings show how the answer works.
To HITCH something is to attach or secure it, often to another object for support or movement.
To LASH objects is to bind them firmly together, commonly by wrapping and tightening a line around them.
To TETHER is to secure something with a cord, rope or chain so that its movement is limited.
To TIE is to fasten, attach or close something by binding material around or through it.
Why this group was difficult
- The words have prominent noun meanings
HITCH can be a problem, LASH an eyelash, TETHER a cord and TIE an item of clothing, obscuring the shared verb reading. - The fastening methods are not identical
The words involve different materials and actions, so the connection depends on their broad shared result rather than one technique. - LASH is visually pulled toward EYE
LASH can appear to belong with the body-related word EYE, making its binding verb sense easier to overlook.
How to spot this pattern next time
Check whether words with familiar noun meanings can all become the same part of speech; here, reading the candidates as verbs exposes the shared action.
Accept differences in material or method when the result is exact: each action secures or attaches something, which is enough for FASTEN.
Four useful facts behind the group
- The official category is exactly FASTEN.
- All four entries function as verbs in this group.
