易错句子I had a stomatic ache all night after eating too much.
正确表达I had a stomach ache all night after eating too much.
stomatic 是植物学形容词，只表示“气孔的”，与“胃”无关；表示“胃痛”的名词搭配是 stomach ache，不能因为拼写接近 stomach 就写成 stomatic ache。

易错句子Each stomatic is surrounded by two guard cells.
正确表达Each stoma is surrounded by two guard cells.
stomatic 是形容词，不能作名词指“气孔”这个结构；单个气孔的名词是 stoma（复数 stomata），作句子主语要用 Each stoma。
两词只差开头一个字母，但 somatic 指“身体的、体细胞的”（如 somatic cells 体细胞、somatic pain 躯体痛），属于医学与生物学用语；stomatic 来自 stoma（气孔），只指植物的气孔，不能用来形容人体。
stomachic 由 stomach（胃）派生，指与胃有关的或健胃的，多作药学术语；stomatic 由 stoma（气孔）派生，指植物气孔。拼写上 stomachic 多一个 -ch-，含义与身体消化器官相关，二者不可互换。
这两个词意思相同，都表示“气孔的”，指气孔的开闭、密度等；stomatal 是植物学文献中最常用的标准形式，stomatic 则是较少见的异体形式，二者可以互换，但要注意别把 stomatic 误读成 somatic。
