tower, tall building, palace
閣 centers on a tall, imposing structure: a tower, a tall building, or a palace. It suggests something elevated and grand.
閣 combines 門 (gate) with 各, which likely contributes the sound. The character originally referred to a gatehouse or a tall structure with a gate, later extending to towers and palaces.
A gate 門 with 各 inside: imagine each (各) floor of a tall tower behind a grand gate. The gate opens to reveal a towering palace.
For カク, picture a tall tower shaped like a cock (rooster) crowing at dawn: cock -> カク, and the tower stands tall like a proud rooster.
