Which word best describes something that cannot be perceived by the senses?

The term "intangible" refers to something that cannot be perceived or touched through the physical senses. It describes qualities, feelings, or concepts that exist but do not have a physical presence or cannot be directly experienced through sight, sound, touch, taste, or smell. For instance, emotions like love or concepts like freedom are considered intangible because they cannot be physically measured or perceived like a solid object.

The other choices present different meanings that do not align with the definition of being imperceptible by the senses. "Inundate" refers to overwhelming someone with things to deal with, "judicious" describes someone who shows good judgment or wisdom, and "laudatory" pertains to expressions of praise. None of these terms capture the essence of something that is not perceivable by the senses, making "intangible" the best descriptor for that characteristic.
