衛生間、大解、小解等的不同的表達
之一：廁所
美國
restroom
bathroom
washroom
men's room=gent's room
ladies' room=powder room
lavatory(飛機上)
latrine(軍中)
英國
toilet
loo(May I use your loo?)
偶爾W.C.(water closet)
幾乎不用bathroom，因為英國傳統居民住房是最普遍的semi-detached house（兩家挨在一起的房子），分上下兩層，上層主人使用，洗手間內有衛浴設施；下層洗手間給客人使用，一般只有馬桶和洗手池。
其他
(portable) john 指戶外的流動型廁所
之二：小解
to urinate = to piss = to take a piss = to take a leak = to void = to empty

?醫生：Do you have trouble urinating?=Do you have difficulty voiding?(小解有困難嗎？)
The manual labours have to use (portable) johns during their working hours.（勞動者在工作時間內需要使用流動性廁所。）

My?urine?is?cloudy?and?it?smells?strong.（有濁尿，味道很重）
I?have?pus?（或air）in?urine.（尿有泡沫）?（pus?=?cloudy;?air?=?bubble）
I?dribble?a?little?urine?after?I?have?finished?urinating.（小便后還會滴滴答答。）（即失禁毛病）
I?am?passing?less?urine?than?usual.（小便的量比平時少）
