Meaning
The kanji 過 (ka, su.giru) is a versatile character with core meanings like 'passing,' 'going beyond,' 'exceeding,' and also 'error' or 'fault.' Its wide range of applications makes it essential for expressing concepts related to time, actions, and judgments.
Historically, 過 is a phono-semantic compound. It combines the radical 辶 (しんにょう), which represents 'movement' or 'a road,' with the phonetic component 咼 (か). This component 咼 itself suggests something 'crooked,' 'askew,' or 'awry.' When these two parts are combined, the kanji originally conveyed the idea of 'moving along a crooked or erroneous path.' This directly led to its meanings of 'passing by' a correct point, 'exceeding' a limit, or making a 'mistake.' The 'movement' aspect from 辶 is clear, while 咼 hints at the deviation or transgression inherent in 'passing beyond' or 'making an error.'
This etymology helps connect the seemingly disparate meanings. Whether you're 'passing' time, 'exceeding' a speed limit, or committing an 'error,' the underlying idea is always a progression or a deviation from a norm or a specific point. With 12 strokes, this kanji is taught in the 6th grade in elementary school. It's a relatively common and essential character in daily Japanese.

Memory Tip
To remember 過 (pass, exceed, error), think of its two main components. On the left, 辶 (しんにょう), is the 'road' radical, which suggests movement or passing along a path. On the right is 咼, implying something 'crooked' or 'askew.'
Imagine someone traveling down a road (辶) but taking a crooked path (咼). This causes them to pass the correct turning point or make a mistake. This visual of moving yet deviating effectively ties together the meanings of 'passing (by),' 'exceeding (a limit),' and 'making an error.' You are moving forward, but a 'crookedness' leads you 'over' a limit or 'wrong.'
