Definition
A 'fellow traveller' is someone who sympathizes with or supports a particular ideology or group without being a formal member. Imagine a friend who always agrees with the environmental club's ideas but isn't actually in the club. They share similar beliefs and offer support, but they're not officially committed. The term implies a degree of alignment without full responsibility or dedication. It's like being an ally without signing up for the whole journey. This term often carries a slightly negative connotation, suggesting a hidden agenda or naive support.
