Which word in Vietnamese retains the same meaning if the grave accent is replaced with a grave accent?

If you think carefully, this puzzle is not difficult at all.

Changing the tone of a word in Vietnamese can completely change its meaning. For example, the word 'bug', if the heavy tone is replaced by a grave tone, becomes a different animal (cow). Likewise, the word 'oven', if the heavy tone is replaced by a grave tone, becomes a completely different object (jar).

However, there are also many exceptions where replacing the grave accent with a grave accent still retains the same meaning. Think carefully to find out which word can replace the grave accent with a grave accent still retains the same meaning?
