罐头

canned goods
🥫 罐头 = 罐 (jar/can) + 头 (noun-suffix); the 头 just marks it as a thing
罐 alone means jar or pot; adding the suffix 头 turns it into the everyday word for a sealed tin or can of food. Many concrete-object nouns in Chinese take this same 头 ending, like 石头 (stone).
罐 — 缶 (jar) radical + 雚 (heron) phonetic
罐 is a semantic-phonetic compound. The 缶 element on the left means 'earthen jar or pottery vessel' and gives the meaning, while 雚 (a type of heron) on the right supplies the sound, related to 'guàn'. Originally referring to clay pots, it now denotes any can, jar, or tin.
头 — 页 (head/page) + 豆 (bean, phonetic)
The traditional form 頭 combines 頁 (xié), meaning 'head', with 豆 (dòu) as the phonetic component. 頁 itself originally depicted a person with an emphasized head. The simplified form 头 is a modern shorthand that replaces 豆+頁 with a simpler shape while keeping the same meaning of 'head' or 'top'.
