“优先购买权”常见的英文表达是 “pre-emptive right” 或 “right of first refusal”。
pre-emptive right：强调在他人之前有优先采取行动（购买）的权利，侧重于“先发制人”的意味。
right of first refusal：更侧重于当所有者有意出售时，持有该权利的人有优先拒绝他人购买而自己购买的权利，重点在于“拒绝他人优先自己” 。
例句：
Shareholders usually have a pre-emptive right to buy additional shares. （股东通常拥有优先购买额外股份的权利。）
The tenant was given a right of first refusal if the property was put up for sale. （如果该房产要出售，租户有优先购买权 。）
