From https://www.google.fi/search?q=termination+analysis and https://en.wikipedia.org/wiki/Termination_analysis : "In computer science, termination analysis is program analysis which attempts to determine whether the evaluation of a given program halts for each input. This means to determine whether the input program computes a total function." So the term "termination analysis" is already defined. The derived term "termination analyzer" means a performer of termination analysis. That does not agree with the propsed defintion above so a differnt term should be used. That "termination analysis" is a know term that need not be defined is demostrated e.g. by https://arxiv.org/pdf/2101.09783 which simply assumes that readers know (at least approximately) what the term means. -- Mikko
