| alfa erradiazio | alpha radiation (A stream of alpha particles which are ejected from many radioactive substances having a penetrating power of a few cm in air but can be stopped by a thin piece of paper) | |
| alferrik galtze | wastage (Extravagant or useless consumption or expenditures) | |
| alga | alga (Simple, green, aquatic plants without stems, roots or leaves. They are among the microscopic organisms that form the start of the food chain. Algae are found floating in the sea and fresh water, but they also grow on the surface of damp walls, rocks, the bark of trees and on soil. They contain chlorophyll and other pigments that let them grow by photosynthesis. On land, algae can be useful in improving the fertility of soil by nitrogen fixation) | |
| alga berde-urdin | blue-green alga (Microorganisms, formerly classified as algae but now regarded as bacteria, including nostoc, which contain a blue pigment in addition to chlorophyll) | |
| algen ugaltze | algal bloom (Excessive and rapid growth of algae and other aquatic plants when they are stimulated to grow too quickly by pollution. It takes place when there are too many nutrients in the water and is aggravated when accompanied by a rise in temperature. Although the algae grow quickly they soon die because they have swallowed up all the water's nutrients. As they decompose they tend to rise to the surface and form a green slime. Algal bloom have increased because higher levels of nitrogen and phosphates from agricultural areas have leached from the fields into water courses) | |

Paraffin waxs consists mainly of higher alkanes) | |
| alkil-konposatu | alkyl compound (Compound containing one or more alkyl radicals) | |
| alkohol | alcohol (A group of organic chemical compounds composed of carbon, hydrogen, and oxygen. The molecules in the series vary in chain length and are composed of a hydrocarbon plus a hydroxyl group. Alcohol includes methanol and ethanol) | |
| alkohol erregai | fuel alcohol (Alternative source of energy for motor vehicles. It is produced by fermentation of sugar cane by the yeast Saccharomyces cerevisiae) | |
| almidoi | starch (A polysaccharide which is a combination of many monosaccharide molecules, made during photosynthesis and stored as starch grains in many plants) | |
| alorren hondatze | field damage (A decline in the productivity of an area of land or in its ability to support natural ecosystems or types of agriculture. Degradation may be caused by a variety of factors, including inappropriate land management techniques, soil erosion, salinity, flooding, clearing, pests, pollution, climatic factors, or progressive urbanization) | |
| altitude | altitude (1. In general, a term used to describe a topographic eminence. 2. A specific altitude or height above a given level. 3. In surveying, the term refers to the angle between the horizontal and a point at a higher level) | |
| altitude gutxiko hegaldi | low-level flight (Flying at low altitude) | |
| alturako arrantza | deep sea fishing (Fishing in the deepest parts of the sea) | |
