1. Curriculum vitae (course of life)
Writing & Everyday · Latin Abbreviations · also used in education
A detailed record of a person's education, work history, publications and achievements submitted with job and academic applications. In the UK, Ireland, India and much of the world it is the ordinary word for a résumé; in the US it usually means a longer academic, scientific or medical record.
Example: Please send a cover letter and a two-page CV to the hiring committee by 30 September.
The plural is curricula vitae, or simply CVs. An American academic CV has no length limit and lists every publication, talk and grant, whereas a résumé is typically one or two pages. Periods (C.V.) are now rare. Vitae is genitive singular, so "curriculum vita" is a mistaken form, and the pronunciation varies between "VEE-tie" and "VYE-tee."
2. Computer vision
Technology & Computing · Artificial Intelligence Abbreviations
The field of AI that enables computers to interpret images and video, including recognizing objects and faces, reading text, tracking motion and reconstructing 3D scenes. It underpins self-driving cars, medical imaging, factory inspection and photo apps.
Example: The CV system spots damaged boxes on the conveyor and diverts them for inspection.
Research dates to the 1960s; a famous 1966 MIT summer project expected to solve basic vision in a few months. The ImageNet dataset and deep convolutional networks from 2012 onward transformed the field, and OpenCV is the most widely used open-source library. In machine learning papers CV can also mean cross-validation, and in job hunting a curriculum vitae; images and cameras point to this meaning.
3. Cabo Verde
Geography & Places · Country Code Abbreviations
Atlantic island nation off West Africa that asked the world in 2013 to stop translating its name as Cape Verde. Cabo Verde's capital is Praia, and its alpha-3 code is CPV.
Example: Flights from Lisbon to Sal, CV take about four hours.
Cabo Verde's diaspora is larger than its resident population of about half a million. CV also means curriculum vitae, the résumé used in most countries outside the US.
4. Coefficient of variation
Units & Measurements · Statistics Abbreviations
The standard deviation divided by the mean, often given as a percentage. It compares variability across data sets with different units or scales, such as the precision of laboratory assays.
Example: The assay's intra-run CV was 3.5%, within the manufacturer's limit.
CV is meaningful only for ratio-scale data with a true zero and a positive mean; it makes no sense for temperatures in Celsius. Clinical laboratories commonly expect CVs below about 5 to 10 percent for routine assays. Outside statistics, CV usually means curriculum vitae.
5. Cross-validation
Technology & Computing · Artificial Intelligence Abbreviations
A method for estimating how well a model will perform on unseen data by splitting the dataset into several folds, training on all but one and testing on the remaining fold, then rotating and averaging the results.
Example: Five-fold CV gave an average accuracy of 87 percent with low variance across folds.
K-fold with five or ten folds is the most common form; stratified versions keep class proportions in each fold, and time-series data needs forward-chaining splits to avoid leaking the future. scikit-learn's cross_val_score is a standard tool. In AI writing CV also means computer vision; mentions of folds, splits and validation scores point to this meaning.
6. Constant velocity joint
Transportation & Travel · Automotive Abbreviations
Flexible joint on a vehicle's axle shafts that transfers power to the wheels at a constant speed while allowing them to steer and move up and down with the suspension. Front-wheel-drive cars have CV joints at both ends of each front axle.
Example: A clicking noise when turning sharply usually means a worn outer CV joint.
CV joints are protected by rubber boots filled with grease; a torn boot lets grease out and dirt in, leading to failure. Replacing the whole axle shaft is often cheaper than rebuilding the joint. In employment, CV means curriculum vitae, an unrelated meaning.
7. Cove (Cv)
Geography & Places · Address Abbreviations
A small sheltered bay or, inland, a recess in a hillside; in Tennessee, Mississippi and other Southern states Cove often names a short dead-end street.
Example: The address is 6 Heron Cv, the last house before the water.
CV is standard for Cove. In Memphis and nearby areas Cove is used much as Court is elsewhere, for cul-de-sacs. CV also means curriculum vitae.
8. Cost variance
Business & Finance · Project Management Abbreviations
Earned value minus actual cost; a negative cost variance means the completed work has cost more than budgeted.
Example: CV is -$40,000, so we need a recovery plan.
Expressed as a percentage, CV% equals CV divided by EV. In job applications, CV means curriculum vitae.
