Je was op zoek naar: machachari (Swahili - Engels)

kwa kitendo chake hiki kipya zaidi ya vyote, sitaki tena kumuelezea zaid kama “mtu mwenye maamuzi machachari”.
with his latest action, i no longer want to describe zaid as a "maverick".

siwezi kuelezea jinsi gani zaid ibrahim ambaye wakati fulani alielezewa kama “mtu mwenye maamuzi machachari”, amekwenda chini katika njia hii.
i can't explain how zaid ibrahim, whom i once described as "maverick", has gone down this way.

wakati wagombea wa awali walikuwa wapya kabisa wasiofahamika sana, wanasiasa wachache machachari wanaofahamika wanatarajiwa kugombea akiwemo rais wa zamani didier ratsiraka, rais wa sasa wa mpito andry rajoelina na mke wa rais wa zamani ravalomanana, anayeitwa lalao ravalomanana.
while the earlier candidates were relatively new to the general public, a few prominent political players from the past are expected to contest: former president didier ratsiraka, current president of the transition andry rajoelina and the spouse of former president ravalomanana, lalao ravalomanana.

mtu mwenye maamuzi machachari ni mtu wa aina ya pekee, mtu ambaye anathubutu kwenda kinyume cha mkondo, mtu unayemheshimu – hata kwa manung’uniko – kutokana na kanuni au misimamo yake.
a maverick is unique, someone who dares go against the flow, a person you respect - even grudgingly - for his principles.
