Selected source glosses provide context, not a complete modern definition inventory

From spike (“kind of inflorescence in which sessile flowers are arranged on an unbranched elongated axis”) + -y (suffix forming adjectives with the sense “having the quality of”). Spike is derived from Middle English spik, spike (“ear of grain; clove of garlic; plant having spikes; plant of the genus Valeriana, especially Valeriana officinalis; plant of the genus Lavandula, lavender”), from Latin spīca (“ear, head, or spike of grain; plant spike”) (feminine) (also rarely spīcum (neuter) and spīcus (masculine)), possibly ultimately from Proto-Indo-European *spey- (“long; sharp; thin”).

Source etymology 2

Original entry ↗
adj

Having one or more spikes; spiny. · Resembling spikes: erect and having sharp points; spikelike. · Of a person or their nature: difficult to deal with; abrasive, hostile, unfriendly. · Of a thing: not smooth; rough, sharp.

Selected source glosses provide context, not a complete modern definition inventory

From spike (“piece of pointed metal, etc.”) + -y (suffix forming adjectives with the sense “having the quality of”). Spike is derived from Middle English spik, spike (“large metal (usually iron) nail; thing shaped like such a nail”); further etymology uncertain, possibly from Middle Dutch spiker (“large nail”), Middle Low German spiker (“large nail”), or Old Norse spík (“spike; sprig”), all possibly from Latin spīca (“ear, head, or spike of grain; plant spike”) (see further at etymology 1), or from Proto-Germanic *spīkō (“large nail, spike”), both ultimately from Proto-Indo-European *spey- (“long; sharp; thin”).
