Just becos the  threads share the common memory space. The memory allocated to the main thread will be shared by all other child threads.

  Whereas in case of Process, the child process are in need to allocate the seperate memory space.

It is called light weight process to emphasize the fact that a thread is like a process but is more efficient and uses fewer resources( n hence "lighter")and they also share the address space.

to add to this,

while creating a process you need to do a lot allocate space, maintain pointer, create a lot of pointer as you see in the block diagram of the process on contrary thread creation is pretty much simple they share the heap of process and just need a stack of their own so it is light weight .

thread is a lightweight process becoz it simply divides a process into various subprocesses....each subprocess completes specific task and these threads run symoultaneously(parallel) resulting in speedy process completion & reduced resource usage..hence less load on O.S.
correct me if m wrong.thx

A Thread is the smallest unit of execution.
Creating a new process would require allocating a new address space, new stack and heap section

But when a process creates one or more threads they share the data and the code section of the parent process. Each thread has it's own copy of Program counter, registers.

Also less overhead in context switch.

Thread is light weight because thread shared the same memory address space and It takes less memory and less time to execute the program.

Thread is a light weight process because it shares its address space except the stack and also it is more efficient than a process.

Just because the threads share the common memory space. The memory allocated to the main thread will be shared by all other child threads.

Whereas in case of Process, the child process are in need to allocate the separate memory space.
