Must the clutch be fully depressed when shifting gears?

[StLondon]

When shifting gears, the clutch must be fully depressed. Specific reasons: The travel distance where the clutch contacts the transmission gears varies for each vehicle—some have longer travel, while others have shorter. As long as the clutch is depressed enough to disengage from the transmission gears, shifting is possible. However, the clutch must be depressed every time you shift. Clutch-related explanation: The principle of fully depressing the clutch when shifting is to completely separate the engine from the transmission gears. This allows the gear lever to change the gear set before re-engaging. Since the gear sets before and after shifting are different, there is a speed difference between the gear sets to be engaged after shifting, which is synchronized by the synchronizer. Consequences of not fully depressing the clutch: If the clutch is not fully depressed during the shifting process, there will be a significant speed difference between the shifting gear set and the transmission gear set, making smooth engagement difficult. At best, this will accelerate wear; at worst, it can cause gear grinding and damage the transmission.
