Portion and allot both mean to give something out. Portion stresses dividing a whole into shares, often for food. Allot stresses formally assigning a fixed share, like time or money, following a rule. The noun use of portion, meaning 'a part', is not compared here.

两者都指把某物分给他人或各方，但 portion 更强调把整体切分成若干份，常用于食物或资源的分割；allot 更强调按规则或权限正式地指派一份定额，常见于时间、任务、预算等场合。此处不比较 portion 作名词表示“一份、一部分”的用法。
