The kanji 激 is a phono-semantic compound. It combines the water radical (氵 - さんずい, "water") on the left with the phonetic component 敬 (kei), which suggests the sound and a related meaning of "respect" or "revere". The combination originally depicted water being agitated or stirred up, hence the meanings related to intensity and agitation. Over time, it expanded to encompass broader meanings of intensity and force, not limited to water.
