Is German hard to learn for English speakers?

German is harder than Spanish or French for an English speaker, and easier than its reputation. The US diplomats' language school puts it in a category of its own at 36 weeks of full-time study, between the Romance languages at 30 and Russian or Polish at about about 44 — and the reasons it takes longer are specific enough to measure. The short version: the words are not the problem. The grammar that holds them together is.

The easy part: the words

German and English are close relatives, and it shows in the everyday vocabulary: Haus, Wasser, Hand, Buch, kommen, gut. More surprising is how fast German's vocabulary pays off. On film and television dialogue, the first 1,000 German word forms cover 77.6% of what is said — more than Spanish, Italian or Portuguese, and second only to French among the languages we measured. The comparison is in which language has the steepest frequency curve.

The long tail: compounds

German's curve starts fast and finishes slowly. To cover 95% of its dialogue, German needs 21,502 different word forms — the most of the five big European languages we measured (Spanish needs 20,854, French 13,909). That figure is for the full corpus; on samples of equal size every language needs fewer, and German still needs the most, 15,367.

The reason is compounding. German joins words into new ones — Kindergarten, Handschuh (hand-shoe, a glove) — and every compound, and every ending on it, counts as a word of its own. 25.2% of the different words in German subtitles are fifteen letters or longer, against a few per cent in the Romance languages, but together those long words are only 0.58% of what is actually said. They make German look harder on paper than it is to listen to. How many words you need to speak German measures this in detail.

The hard part: the grammar

German keeps grammatical machinery that English has largely lost. Wikipedia's summary of German grammar puts it plainly: there are 3 genders and 4 cases, and a main clause has strict verb-second word order.

Genders. Every noun is masculine, feminine or neuter, and the gender is mostly not predictable from the meaning: it is der Löffel (spoon, masculine), die Gabel (fork, feminine) and das Messer (knife, neuter). The gender has to be learned with the word.

Cases. The article changes with the noun's job in the sentence. English has one word for "the"; German has six spellings of it — der, die, das, den, dem, des — and together those six make up 5.7% of every word spoken in German film and television dialogue. (Some of those are pronouns — die and das also mean "that" or "those" — but it is still a measure of how constantly a German speaker is choosing among them.)

Word order. In a main clause the verb comes second, whatever comes first: Heute gehe ich — "today go I". In a subordinate clause it moves to the end: weil ich heute nach Hause gehe, "because I today home go". Separable verbs split in two: Ich rufe dich morgen an, "I call you tomorrow up".

None of this is exotic, and all of it is regular enough to learn. But it is present in nearly every sentence, which is why German takes the extra weeks.

So is German hard?

• Vocabulary: easier than you fear — familiar roots, and the second-fastest start of the languages we measured.
• Grammar: harder than any of the Romance languages, because genders, cases and word order all have to be right at once.

The overall picture, with every language side by side, is in the hardest languages to learn for English speakers. If you want to see how many German words you already know, German words used in English measures the ones English borrowed.

The 1,000 most common German words are free and in frequency order, and can be downloaded as a printable PDF or a CSV for Excel or Anki. The German course teaches the grammar alongside them, one point at a time.

Where those extra weeks fall, level by level, and what the Goethe-Institut estimates for each, is in how long it takes to learn German; how often the split verbs turn up is measured in the 100 most common German verbs.
