週
부수: 辶
획수: 11획
週 has the meanings period and week.
週 = 周 + 辶
X = semantic/phonetic + semantic
• 周 originates from 
meaning ‘field’ (see below).
• 辶 is an abbreviation of 辵 and represents the meaning ‘to walk’.
Evolution:
週 = to return ➔ to go around ➔ cycle ➔ period of time ➔ week
週 = to return ➔ to go around ➔ circle ➔ complete
周 = 
+ 口
• is an earlier form of 田 meaning ‘field’. Think of how ‘going around’ a designated farm boundary defines its ‘circumference’.
• 口 is a distinguishing mark added to when the original became used as a proper noun.
辵 = 彳 + 止
• 彳 is taken from 行 meaning ‘road intersection’.
• 止 depicts a foot and represents ‘walking’.
Together they give 辵 the meaning ‘walking down the street’.
Over time, the components 彳 and 止 merged into 辵.
In 週, they were abbreviated to 辶.
Mnemonic
Look at the historical forms to see how became the cross-shape in 周 and how the box 口 was added below this.
Imagine a farmer walking 辶 around the circumference of his rice field . He does this once per week 週 to check on his farm.
