喜樂美語
  1. 1體重過輕、過輕的。醫生講「體重過輕」用這個字，是中性的健康描述，不是罵人。也可以講東西「重量不足」（包裹、貨品）。注意台灣說「太瘦」比較接近 too thin，thin 講的是外表，underweight 講的是磅秤上的數字低於健康標準。

    Underweight means weighing less than you should. It is used most often about people and about health: a doctor says a baby, a patient, a teenager is underweight, meaning their weight is below the healthy range for their age and height. That is the main use, and it is a medical, neutral word — the doctor is not anyone, just reporting a number. It also works for things: an underweight parcel, an underweight bag of rice, meaning it does not reach the weight it is supposed to be. Two things to notice. First, it is an adjective, and it comes after the verb far more often than before the noun — "he is underweight" is normal English; "an underweight child" is fine too but a little more written. Second, it is genuinely neutral in a way that its opposite is not: "overweight" carries social weight and can hurt, while "underweight" mostly sounds like a health concern. Though actually, that is changing a little — because being thin is admired in Taiwan and elsewhere, some young people hear "you're underweight" as a compliment, which is not at all how a doctor means it. There is also a noun, "underweight", but you will almost never meet it outside medical writing.

組成under- (below) + weight (how heavy something is). Both halves are ordinary old English words, so the meaning really is just what it says: below the weight. English has a whole shelf of these — underweight, undersized, underage, underpaid.
