The phrase "by memory" is often used to describe something that is memorized and not written down. Its spelling can be explained using the International Phonetic Alphabet (IPA). The first word, "by," is spelled /baɪ/ with a long "i" sound (represented by the symbol /aɪ/). The second word, "memory," is spelled /ˈmeməri/ with a schwa sound (represented by the symbol /ə/) in the second syllable. In summary, "by memory" can be written phonetically as /baɪ ˈmeməri/.
"By memory" refers to the ability to recall or reproduce something solely based on the information stored in one's memory, without relying on any external aids or references. It implies the act of remembering or reiterating something without consulting written notes, electronic devices, or any other form of assistance.
When someone performs a task "by memory," they rely on their own mental faculties to access the information or knowledge required. This can apply to a wide range of activities, including reciting a poem, playing a musical instrument, solving a mathematical problem, or executing a series of steps for a specific procedure. It often indicates a high level of familiarity or expertise in a certain subject matter, cultivated through extensive practice, study, or experience.
The ability to do something "by memory" can vary among individuals, with some possessing a remarkable capacity to accurately recall extensive details or complex processes, while others may struggle to remember even basic information without external prompts. Factors like concentration, repetition, and overall cognitive abilities can influence one's aptitude for performing tasks "by memory."
By relying solely on memory, individuals demonstrate their proficiency and reliance on their own cognitive capabilities. This skill is often cultivated in educational settings, such as memorizing historical dates, equations, or foreign language vocabulary. While memory can be fallible and subject to forgetting or distortion over time, being able to perform tasks "by memory" highlights human mental dexterity and the capacity to retrieve stored information when needed.
The phrase "by memory" comes from the combination of two distinct components: "by" and "memory".
The term "by" has its roots in Old English and can be traced back to the Germanic word "bi". It has a wide range of uses, but in this context, it is used to indicate a method or means by which something is accomplished or obtained.
The word "memory" can be traced to the Latin term "memoria", which refers to the mental capacity to retain and recall information or experiences. It is derived from the verb "memor", meaning "mindful" or "remembering".
When combined, the phrase "by memory" signifies a process of recalling or performing something solely by relying on one's memory, without the aid of written notes or aids.
