cheap和inexpensive都有"便宜的"、"廉價的"意思，但使用上有所不同。cheap強調"價錢便宜"或"因質量差而價格低"，如I won't buy cheap dresses. 我不愿意買便宜衣服。而inexpensive則指"價值與價格相比的便宜"，表示"價格公道的"、"不貴的"，例如This kind of car is inexpensive. 這種汽車便宜。cheap可作為形容詞，表示"廉價的"、"不貴重的"，貶義詞，有"低劣的"、"價值不大的"、"劣質的"、"可鄙的"、"低級的"、"虛偽的"、"吝嗇的"、"不費力氣的"、"容易得到的"、"體質虛弱的"、"垂頭喪氣的"等含義。例如：an inexpensive fipple flute. 一種非常廉價的哨笛。I am looking for something inexpensive. 我在找不太貴的。I want to buy more inexpensive. 我想買個便宜些的。而inexpensive作為形容詞，表示"不貴重的"、"不昂貴的"，用于描述商品價格合理。如：This kind of car is inexpensive. 這種汽車便宜。Are there any inexpensive restaurants near here? 這附近是否有價位不貴的餐廳？Be there any inexpensive restaurant near here? 這附近是否有價位不貴的餐廳？But they also respond to inexpensive perfumes." 但一些廉價的香水也挺受他們歡迎的。Do you have a more inexpensive room? 你們有沒有便宜的房間？inexpensive accommodations on a ship or train. 在船或火車上的票價很低廉的艙位。綜上所述，cheap側重于價格低，可能伴隨質量低，而inexpensive則更強調價格與價值的匹配度，兩者在使用時需注意語境。
