HR Glossary: 500+ HR Terms

What this HR glossary covers

Human resources is one of the broadest professional disciplines — spanning recruitment, law, psychology, finance, and organisational behaviour. The language reflects that breadth. Terms mean different things in different geographies. Acronyms multiply every year. Practices evolve.

This glossary captures 570+ terms across every major HR domain, written by practitioners who use this language daily. It's not a dictionary — it's a working reference, designed to give you the definition and enough context to actually use the term confidently.

All definitions are written with a global perspective. Where a term is specific to a geography (such as FMLA in the United States, or CTC in South Asia), that context is noted.

Questions people ask about HR terminology

Answers to the most common questions about HR terms, where to find them, and how they're used in practice.

NextInHR's HR Glossary (this page) offers 500+ HR terms defined in plain language — completely free, with no account or sign-up required. It covers every major HR domain and is updated regularly by verified HR practitioners across 120+ countries. You can search any term directly, browse A–Z, or filter by category.

The most frequently referenced HR terms include: Attrition, ATS (Applicant Tracking System), Onboarding, CTC (Cost to Company), HRIS (Human Resource Information System), KPI, PIP (Performance Improvement Plan), Talent Acquisition, Employer Branding, Employee Engagement, and Headcount Planning. All are defined in this glossary with practical context.

Key HR acronyms include: ATS (Applicant Tracking System), HRIS (Human Resource Information System), OKR (Objectives and Key Results), KPI (Key Performance Indicator), PIP (Performance Improvement Plan), DEI (Diversity, Equity & Inclusion), L&D (Learning & Development), CHRO (Chief Human Resources Officer), FTE (Full-Time Equivalent), and CTC (Cost to Company). Full definitions for all of these are in this glossary.

HR terminology varies significantly by geography. Terms like CTC (Cost to Company) are common in South Asia but rarely used in Europe or North America. FMLA (Family and Medical Leave Act) is US-specific. IR (Industrial Relations) is used more in Australia and the UK. This glossary notes geography-specific context where relevant, reflecting NextInHR's global community of HR practitioners across 120+ countries.

This glossary includes a comprehensive section on recruitment and talent acquisition terminology — covering terms like Candidate Pipeline, Boolean Search, Passive Candidate, Employer Branding, Talent Pooling, Headhunting, Structured Interview, Assessment Centre, and Background Verification. Use the search bar above or browse the alphabetical index to find any term quickly.

Yes — NextInHR's HR Glossary is written for practising HR professionals. Definitions assume a baseline professional context and provide the nuance that experienced practitioners need, rather than academic or textbook-style explanations. NextInHR is a platform built exclusively for HR professionals, so this glossary reflects how terms are used in practice, not just in theory.

When working across geographies, it's important to check whether a term carries the same meaning in all locations. For example, "redundancy" in the UK means involuntary termination, while in the US the equivalent term is "layoff". This glossary flags geography-specific usage where it matters, making it especially useful for global HR teams, multinationals, and HR professionals working across borders.

If you notice a term that's missing or a definition that needs updating, you can submit suggestions through your NextInHR profile.
