What makes some languages easier for English speakers to learn than others?

Languages vary in difficulty for English speakers primarily based on how much they share with English in four key areas:

1. Linguistic Genealogy (Language Families) Languages that share a common ancestor with English—the Germanic family—are generally the easiest to learn. Languages like Dutch, German, and the Scandinavian languages often share cognates (words with common origins) and similar grammatical structures. Moving into the Romance family (like Spanish, French, or Italian) is often the next step because, while they come from a different branch, centuries of historical contact have introduced thousands of Latin- and French-derived words into English.

2. Typological Distance This refers to how a language is "built." If a language organizes sentences in the same way English does (Subject-Verb-Object), it feels more intuitive. If it uses a completely different word order (like Japanese, which is Subject-Object-Verb), or relies on complex systems English doesn't use—such as tones (Mandarin or Vietnamese) or extensive case systems (Russian or Finnish)—the cognitive load increases significantly.

3. Writing Systems Languages that use the Latin alphabet are much more accessible to English speakers because the brain doesn't have to learn an entirely new way to decode information. Learning a language that uses a different script (like Arabic, Thai, or Greek) or a logographic system (like Mandarin characters) adds a significant layer of study before you can even begin to read basic sentences.

4. The "Cognate Density" and Cultural Proximity Even if a language is not closely related, it may feel easier if it contains many "loanwords" from English. In today’s globalized world, English has lent words to many languages (especially in technology and business), which can give a learner a head start. Conversely, a language with very little cultural overlap requires learning an entirely new set of concepts and vocabulary with no anchors to English.

In summary: The easier a language is to learn, the more "transfers" your brain can make from English. When the vocabulary, grammar, and script are all different, you are effectively building a new mental architecture from scratch, which is why those languages are typically classified as the most challenging.
