The way I remember einfach means easy and schwer means difficult is like this:
"Einfach" sounds kinda like "infant", and (in my opinion) infants are easy to care for.
And "schwer" kinda sounds like "swear", and people tend to swear in difficult situations
I hope this helps anyone having trouble remembering :)
The basic meaning of einfach is "simple".
Simple things (that aren't complex, i.e. have few parts instead of many) are often easy.
And since bare adjectives are often also used as adverbs in German, it can also mean "simply".
And "simply" is often used to mean "just". (That's simply too much = That's just too much.)
And yes, leicht basically means "light(weight)" but also means "easy".
English uses a metaphor where "hard" things are difficult (so "hard" means not only "stiff, inflexible, rock-like" but also "difficult"), while in German, the metaphor is "heavy" things are difficult (perhaps because it's difficult to lift a heavy weight).
So schwer = heavy; difficult and conversely leicht = light; easy.
No, that doesn't really work.
just can be an adverb or an adjective, as can einfach.
As an adverb, it generally modifies an adjective or a verb.
But there's no adjective in this sentence, so the most natural interpretation would be the adjective just, which means something like "in accordance with justice; fair".
But einfach as an adjective does not mean "fair".
Similarly, the most natural interpretation of Das ist einfach is with einfach as an adjective, meaning "simple", rather than as an adverb, meaning "simply".
One could perhaps imagine that einfach is an adverb modifying the verb ist, i.e. "That simply is, That just is", but that's less likely, and I think the translation as "That is just" would be even less common word order in English.
Well, German, English and Hindi are all part of the Indo-European language family so it’s understandable that knowing Hindi helps you in learning another Indo-European language.
Also, medical terms use a lot of Latin and Greek origin words, which leads you to understand many word roots and affixes.
People often have a larger “language baggage” than they realize. The bigger the language baggage, the easier you learn languages.
Strictly speaking, they are not quite the same thing.
Das ist leicht. = That is easy. (opposite of schwer "difficult")
Das ist einfach. = That is simple. (opposite of kompliziert "complicated")
Simple things are often easy and vice versa, so the two words are often used interchangeably.
