The word "drilled" is spelled with two L's despite the fact that the letter "I" follows the double L's in the word. This is because when two consonants are followed by a vowel, the first consonant is usually doubled in English. In IPA phonetic transcription, "drilled" is transcribed as /drɪld/, with the two L's representing the "l" sound at the end of the word, the "i" represented by the "ɪ" sound, and the "d" represented by the "d" sound at the beginning and end of the word.
The term "drilled" serves as the past tense verb form of the word "drill." "Drill" refers to a mechanical tool or device designed to create holes or perforations in various materials. When something is "drilled," it means that holes have been made in it using a drill or similar mechanism.
The act of drilling systematically involves applying pressure and rotating the drill, typically with the assistance of an electric motor. This action causes the drill bit, which is the pointed or cutting part of the drill, to penetrate the material being drilled. The result is a hole or cavity, which may vary in size, shape, or depth depending on the individual drilling task or purpose.
Furthermore, the term "drilled" can extend beyond the physical act of creating holes and be applied metaphorically. In this context, "drilled" can refer to a person being subjected to intense or repetitive instruction or training in order to acquire or reinforce a particular skill or knowledge. For instance, someone undergoing rigorous military training can be said to be "drilled" in various tactics and procedures.
Overall, "drilled" refers to the act of creating holes in materials using a drill, as well as the process of imparting intense instruction or training to an individual in a particular subject or skill.

The word "drilled" originates from the Old English verb "drillan", which means "to pierce with a drill". This verb is derived from the Old Norse word "dreila", meaning "to turn round, wind, bore". The Old Norse term ultimately traces back to the Proto-Germanic root "*þreulijaną", which denotes turning or twisting. Over time, the verb "drillan" in Old English evolved into "driellan" and then to "drillen", which finally transformed into "drilled" in its modern form. The term "drilled" has come to refer to the act of creating holes, particularly through the use of a drilling tool.
