Semi-literacy refers to a state where an individual lacks the essential literacy skills necessary for effective communication and comprehension. There are several synonyms for this phrase, including partial literacy, limited literacy, basic literacy, and rudimentary literacy. These synonyms are all used to describe individuals who have some knowledge of language and may be able to read, write, and understand basic concepts, but are not proficient enough to communicate effectively at a higher level. While semi-literacy may be a significant challenge for individuals, the use of these synonyms helps to explain the level of proficiency, and underscores the importance of literacy education and support to help individuals reach their potential.
